Islamic Finance Guide to Investing Your Money Ethically

WHAT IS ISLAMIC FINANCE?

Islamic finance is a financial system based on Sharia principles - the religious law enshrined within Islam. Islamic finance offers an alternative financial system to the conventional systems, and is based on fairness, transparency, and social justice.

WHO USES ISLAMIC FINANCE?

Islamic finance is a growing industry and is used extensively by Muslims throughout the world. However, more and more non Muslims are also looking at Islamic finance services as they want to operate in a more ethical way.

DO MUSLIMS PAY INTEREST IN THE UK?

Whilst Muslims are discouraged from paying or earning interest in any form under Islamic finance rules, many Muslims in the West do pay interest. However, more and more Muslims are becoming aware of alternative financial systems and products that enable them to access loans and financial services that are compliant with Sharia law.

CAN MUSLIMS TAKE LOANS?

Yes, of course. Taking a loan is not prohibited in Islam. However, it is important to ensure that the loan terms are compliant with Sharia rules.

HOW DO ISLAMIC LOANS WORK?

Islamic loans are structured and developed to ensure they are halal - that is they do not contravene any rules in Islam relating to finances. For example, an Islamic loan will not have any element of interest attached to it.

WHY CAN'T MUSLIMS EARN INTEREST?

In Islam, interest is seen as exploitative as it leads to the lender making a profit at the expense of the borrower. Islam views interest as the unfair accumulation of the wealthy and this can lead to financial distress for those who need to borrow money. Interest is viewed as being against the promotion of social justice and economic fairness which are key concepts underpinning Islamic finance.

WHAT IS HARAM IN ISLAMIC FINANCE?

The following are deemed haram in Islam: riba/interest, gambling, excessive uncertainty, investment in haram industries or practices.

WHAT IS ETHICAL FINANCE?

While there is no universally accepted definition of ethical finance, the Ethical Finance Hub describes it as "A system of financial management or investment that seeks qualitative outcomes other than purely the management of returns. Outcomes sought may reflect ideas from faith, social, environmental and governance theories."

IS ISLAMIC OR SHARIA-COMPLIANT FINANCE ETHICAL?

The World Bank mentions that Islamic finance is ethical, sustainable, environmentally and socially responsible finance. It promotes risk sharing, connects the financial sector with the real economy, and emphasizes financial inclusion and social welfare.

While there is no universally accepted definition of ethical finance, the Ethical Finance Hub describes it as "A system of financial management or investment that seeks qualitative outcomes other than purely the management of returns.

Green investments or sustainable investments are those that are deemed to be socially responsible with a positive impact on the environment and wider society. As a complete financial system, Islamic finance facilitates green investments and what this means for investors is an increase in sustainability growth. When green investment and Islamic finance come together they drive sustainable growth.

Islamic finance is growing in popularity and was a system devised many centuries ago. In comparison, the green industry is relatively new. Islamic finance's emphasis on economic justice and focusing on marginalised communities and organisations is the foundation of its principles.There are increasing collaborations between the green industry and the Islamic finance industry.

They complement each other and offer benefits for organisations, and both client and customer.

WHAT ARE GREEN INVESTMENTS?

Green investments are also known as socially responsible investments or sustainable investments. They are centred on those investments that positively affect society, organisations, and people.

Green investments range from renewable energy, to clean technology, sustainable agriculture, green bonds to impact investing.

Green investing aims to ensure that investors who want to align their financial transactions with their ethics can do so. That is not to say that green market investments do not provide good financial returns. On the contrary, like Islamic finance, green investing has proven to be revenue generating whilst also being eco-friendly.

Types Of Islamic Finance Based Green Investments

The kinds of Islamically compliant green investments are wide ranging. They cross various industries from agriculture, to environmental protection, to clean technology. Both Islamic finance and green investments focus on equity, regulation, risk management ,and understanding the needs of the parties.

ESG, that is environmental, social and corporate governance are all key considerations. Islamic finance is the financial tool that an institution can use to remain Sharia compliant and green focused.

With the alignment of both the green industry and Islamic finance, there are a great deal of products on the market now that are tailored to be green and Sharia compliant.

Let's have a look at some green products that are Islamic finance compliant:

  • Ethical mutual funds: these kinds of mutual funds are managed in accordance with Sharia rules. When it comes to the actual investment, these kinds of funds only invest in projects and companies that meet both the Islamic finance and green criteria.
  • Green sukuk: these sukuks are a type of bond that raise funds for projects that are environmentally sound and sustainable. The sukuks have to be Sharia compliant for them to be halal. Projects range from providing capital for clean water initiatives, decarbonisation, to renewable energy, technology, and agriculture.
  • Real estate: green real estate funds invest in sustainable real estate projects and are financed by money that is generated and spent in accordance with Sharia rules. This means any loan comes without any interest payments being charged or paid. Often, ethical real estate investments take place in areas of crisis with a view to enabling local communities to transition away from the crisis in an affordable and ethical way.
  • Microfinance: Islamic microfinance services and products are increasing in popularity. This is mainly due to them being regulated in the same way in the UK as other non-Islamic finance products (although, you must always do your own research - knowledge is key). Islamic microfinance can offer funding to SME businesses and individuals who are engaged in eco-friendly ventures and sustainable growth.
  • Islamic stocks: if you look carefully you will see there are various Islamic stocks on the market that are green and sustainable. These stocks are usually in companies that are green focused and ethically sound.
  • Islamic crowdfunding: when looking at sustainable and ethical finance models, then Islamic crowdfunding ticks all the boxes. For those with aspirations of raising funds for green projects, Islamic crowdfunding offers a great alternative for raising start-up funds.

Commonalities Between Islamic Finance And Green Investments


Both green investing and Islamic finance have many points of convergence and commonality. As models of investment, they complement each other. Both encourage and promote social responsibility and ethical investing.

It is important to remember that both green investment and Islamic finance have foundations in ethics, justice and social responsibilities. It therefore makes perfect sense that they are great partners in the financial world.

In addition, both Islamic finance and green investing principles share the following key principles:

  • Prohibiting harmful activities and industries: one of the main rules of Islam is that we should stay away from harmful activities and industries. This means a prohibition in investing, managing or working in industries such as the porn industry, and the alcohol and gambling industries. Similarly, green investments tend to stay away from these industries as they serve no real green benefit to society.
  • Sustainable development goals: Islamic finance and green investing play a significant role in promoting sustainable development goals. So, how is this achieved? it is done through the encouragement and support of economic growth, social wellbeing and environmental sustainability.
  • Assessing the impact on society: both Islamic finance and green investments are focused on benefiting society as a whole. The aim is to positively impact society and sustainable development, whilst trying to ensure that wealth inequality is reduced and there is economic justice. Investing in industries that tackle climate change, poverty reduction, renewable energy, education, research, and innovation are referred over more profit based industries.
  • Ethical screening behaviours and tools: in order to ensure that the investments are compliant with both Sharia laws and green principles, ethical screening is high on the agenda. Both the green investment industry and Islamic finance focus on ensuring that investments and industries are screened, their governance is clear, and policies are not exploitative.

HOW DOES ISLAMIC FINANCE RELATE TO SUSTAINABILITY?

Islamic finance is based on Sharia rules which provide the legal and financial framework within which to live, transact and behave. Islamic finance is more particularly focused on providing rules pertaining to the economy, business and finance.

Due to the very nature of the ethical way Islamic finance operates, this immediately irradicates the purely profit driven and interest based activities of conventional forms of finance.

Islamic finance has always been a key player in achieving and promoting sustainable development goals by:

  • promoting poverty eradication
  • promoting UN goals relating to sustainability
  • Ensuring there is financial inclusion in all countries
  • Holding banks accountable and insisting on interest free services and products
  • promoting health and wellbeing including clean sanitation and renewable energy
  • promoting better education and the eradication of interest based debt
  • having strategies that focus on gender equality
  • encouraging sustainable agriculture and food security projects

For anyone looking for green projects to invest in, in a halal way, then you must consult with financial advisors who are experienced and knowledgeable in both areas.

In the West investors are looking for more conscientious ways to invest. Neither green investment nor Islamic finance are taught at school or featured heavily in the news. However, the impact of the alignment of these 2 distinct industries is becoming more known in investment markets.

This strategic alignment is opening up major market opportunities for investors. ESG financing is expected to see huge growth in the next decade, as is investment in clean technology and net zero industries. There is clearly an appetite for financial products that are Islamically sound, but also sustainable and green.

Islamic finance, when coupled with green investment, is bridging cultures, finance models and inclusivity. It is an area of finance that is seeing exponential growth in major financial hubs such as London, Washington, Geneva, and Dubai.

ISLAMIC SAVINGS ACCOUNTS - WHAT ARE THEY?

An Islamic savings account, also known as a Sharia compliant savings account, is a type of savings account that is designed to be compliant with Islamic law. Islamic finance rules prohibit the payment and collection of interest, also known as riba.

Instead of interest, Islamic savings accounts typically pay profit or loss sharing. This means that the bank and the customer or account holder share in the losses or profits of the bank's investments.

HOW DO ISLAMIC SAVINGS ACCOUNTS WORK?

Instead of offering interest on deposited funds, an Islamic savings account operates on the principle of profit and loss sharing, where the profits made by the bank are shared between the bank and the account holder.

An Islamic savings must adheres to the principles of Islamic finance. These principles, derived from the teachings of the Quran, prohibit the payment or receipt of interest on financial transactions. The bank offering Islamic savings accounts ensures that the account is not charged or paid any interest.

Islamic savings accounts are also known as interest-free savings accounts or sharia-compliant savings accounts offer a number of benefits to those who choose to use them.

Conventional Savings Accounts


To compare, conventional ISAs are a type of savings account offered by banks and financial institutions in the United Kingdom. ISAs are regulated by the Financial Conduct Authority (FCA).

Conventional ISAs are essentially offer the customer to save money and earn interest on their savings without having to pay taxes on the interest earned. The main difference between a conventional ISA and an Islamic savings account is they way in which they earn money for the account holder.

Islamic Savings Accounts And Sharia Rules

An Islamic savings account, also known as an Islamic finance account or a Shariah-compliant savings account, is a type of financial account that is designed to be compliant with the principles of Islamic law (Shariah). In contrast, a conventional ISA, or Individual Savings Account, is a type of savings account that is offered by traditional banks and financial institutions in the UK.

One of the key differences between these two types of savings accounts is the interest rate. Islamic law prohibits the charging of interest, known as riba, on loans and financial transactions. Therefore, an Islamic savings account does not offer interest on to customers on the deposited funds.

Instead, an Islamic savings account operates on the principle of profit and loss sharing, where the profits made by the bank are shared between the bank and the customer or account holder. This means that the returns on an Islamic savings account may vary depending on the performance of the bank.

Ethical And Socially Responsible Investments

Another key difference between Islamic and conventional savings accounts is the use of investments that are considered to be ethically and socially responsible.

Islamic finance is based on the principle of avoiding investments in businesses that are considered to be harmful to society, such as those involved in the production of alcohol, tobacco, gambling, and other activities that are prohibited by Islamic law. Conventional ISAs, on the other hand, do not have any restrictions on the types of investments that can be made with the deposited funds.

Taxation Of Islamic And Conventional Savings Accounts


In addition to the differences in interest rates and investments, there are also some differences in the way that Islamic and conventional savings accounts are taxed.

In the UK, ISAs are tax-free savings vehicles, meaning that the interest earned on the deposited funds is not subject to income tax. However, the profits earned on an Islamic savings account may be subject to income tax, depending on the specific details of the account and the tax laws in the country where it is based.

It is always best to find out as much information about the savings account you are opening. The bank or provider of the service should be able to help you identify the exact tax implications for you. A comparison of the accounts can also be done via the website of the bank.

Overall, the main difference between an Islamic savings account and a conventional ISA is the way they are structures and the principles each account is based upon.

Structuring Of Conventional Savings Accounts Vs Islamic Savings Accounts


Islamic savings accounts are designed to be compliant with the principles of Islamic finance, this includes the prohibition of interest and the promotion of socially responsible investments. Islamic savings accounts need to ensure they are structured in a way that does not contravene any Islamic finance principles. The structure and the way they progress are important components as the obligation to be Sharia compliant applies to the lifetime of the savings account.

What this means is that the bank offering Sharia compliant savings accounts must ensure it meets all the Islamic finance requirements of operating such an account.

Conventional ISAs tend to be more flexible and do not have the same restrictions as an Islamic savings account would have. However, for Muslims and other customers who do want an ethical form of saving, Islamic savings accounts are useful tools for saving in a Sharia compliant way.

It is therefore important to understand the differences between the two types of savings accounts.

The Benefits Of An Islamic Savings Account

There are over a billion Muslims worldwide. As a result, the principles of Islamic finance and banking have gained increasing recognition and popularity in recent years.

One of the key products offered by Islamic finance institutions is the Islamic savings account.

An Islamic savings account must operate in a way that is consistent with the values and beliefs of Islam, including the prohibition of interest (riba) on loans and financial transactions.

There are several benefits to using an Islamic savings account. Here are just a few:

  1. Alignment with religious beliefs: For Muslims, the prohibition on interest is an important religious principle. By choosing an Islamic savings account, individuals can align their financial practices with their religious beliefs.
  2. Higher potential returns: Because Islamic savings accounts do not pay interest, banks and other financial institutions that offer these accounts often provide higher potential returns in other ways. For example, some Islamic savings accounts offer profit-sharing arrangements, where the bank shares a portion of its profits with account holders.
  3. Increased transparency: Islamic finance is based on the principles of transparency and fairness. As a result, Islamic savings accounts often provide greater transparency than traditional savings accounts, with clear and straightforward fee structures and a lack of hidden charges.
  4. Support for ethical investing: Islamic finance prohibits investment in certain industries, such as gambling and alcohol, that are considered sinful in Islam. By choosing an Islamic savings account, individuals can ensure that their money is not being invested in ways that conflict with their religious beliefs.
  5. Contribution to the Islamic finance industry: Islamic finance is a growing industry, with an increasing number of people around the world choosing to use sharia-compliant financial products. By choosing an Islamic savings account, individuals can support the continued growth and development of this industry.
  6. Higher Returns: Because Islamic savings accounts operate on the principle of profit and loss sharing, they may offer higher returns than conventional savings accounts that offer interest. This is because the returns on an Islamic savings account are linked to the performance of the bank, and the profits made by the bank are shared with the account holder. This means that the returns on an Islamic savings account can vary depending on the bank's performance, but they may be higher than the fixed interest rates offered by conventional savings accounts.
  7. Ethical and Socially Responsible Investing: Islamic finance is based on the principles of ethical and socially responsible investing. This means that Islamic finance institutions avoid investing in businesses that are considered to be harmful to society, such as those involved in the production of alcohol, tobacco, gambling, and other activities that are prohibited by Islamic law. By choosing an Islamic savings account, you can ensure that your money is invested in businesses that align with your values and beliefs.

Choosing The Right Savings Account For Your Needs And Values


An Islamic savings account offers a wide range of benefits for savers. Some of these benefits are financial and others are beneficial for those with religious beliefs who want to adhere to Sharia compliant savings.

There has been a significant growth in lenders who are now offering Islamic savings accounts, so it is always worth doing your due diligence to find the right account for you.

Waqf is an ongoing, sustainable, charitable donation and has been used throughout Islamic history to benefit and support communities, and aid community development. Islamically, waqf is a mechanism through which the condition of society can be improved. Waqf refers to an endowment made to a charitable, educational or religious cause.

It is a voluntary action that the whole community can benefit from, for example, the building of a university, research centre or hospital.

WAQF - WHAT DOES IT MEAN?
The Arabic meaning of waqf means 'restriction'. This is based on the principle that all property essentially belongs to Allah. So, whilst a Muslim may donate to a charity for community development, the donation is not owned by the Muslim but by Allah.

For example, if you donate some land or an asset for the purpose of community development, then the community will reap the benefits. The donation releases an ongoing community benefit that supports future generations. A famous example of waqf is the Al Azhar Mosque and University in Cairo, Egypt. This University was founded as waqf in 1908, with funds donated by wealthy Egyptians.

HOW DOES WAQF WORK?
Waqf involves donating a fixed asset which in turn provides a financial return.

Waqf is based on the principle that you can donate an asset that can then continue to provide a charitable service for the foreseeable future. The waqf project goes on to support others in the community through various activities and services.

This is how waqf works:

  • Individual donates an asset to a waqf project.
  • The donations are collated and invested in a Sharia compliant way.
  • Any profits and returns on the investments are used to support charitable organizations such as education, relief of poverty, providing healthcare services and emergency solutions.
  • Some profits are reinvested in a Sharia compliant manner.

The outcome is that your donation should keep going for a number of years, benefiting humans for generations. The incentive for Muslims wanting to donate to a waqf is that the donation is considered to be an ongoing charitable endowment that benefits others for many years.

History Of Waqf

Although waqf is not explicitly prescribed in the Quran like charity is, it is considered to be comparable to sadaqah. Waqf investments are deemed to be a crucial part of Islam as the Prophet (SAW) stated that:

"When a person dies, all their deeds end except three: a continuing charity, beneficial knowledge, and a child who prays for them"

Waqf investments have an important continuing charity element.

Waqf As A Social Finance Institution

Many Muslim majority countries in the world are still developing and income-poor. There is a lack of availability of private sector investment businesses and options. Waqf can be considered a social finance institution that can fill the gaps in development spending. Waqf provides an avenue for the effective utilisation of perpetual social savings.

With transnational waqf investments and support programmes, there is potential for philanthropic Muslims to support the development of communities across the world.

When viewed through an Islamic redistribution framework, it is clear that waqf harnesses selfless charitable giving in a way that is effective and impactful. Targeting social segments within society and aiming for long term improvement brings benefits to donors and society as a whole.

Donating assets for permanent societal benefit facilitates flexibility and stabilisation for deprived and needy communities. Waqf essentially transforms social capital into social infrastructure, complementing zakat and sadaqah donations.

Sourcing Sharia compliant waqf investments and donations online can be difficult, so you must ensure that you undertake the due diligence required.
