Accounting, interest and mixed income: guidance for finance professionals

Accountants, management controllers, auditors, treasurers and finance directors are in a particular position. They neither sell nor produce anything forbidden, yet they record, calculate and certify every flow of money through the business, including interest on loans, financial income and revenue from questionable activities. The hadith that mentions the "scribe" of riba makes the question especially sensitive for them.

This page sets out the views commonly held by scholars, the concept of income purification and ways of reconciling professional obligations with personal convictions. It does not replace the opinion of a qualified scholar or the guidance of a professional accounting body.

The scribe of riba: what does the hadith refer to?

The hadith reported by Muslim curses the one who consumes interest, the one who pays it, the one who writes it down and the two witnesses to it. Commentators explain that the "scribe" is the person who drafts the interest-bearing loan contract, in other words someone who takes part in concluding it. The question is whether recording an interest expense in the books after the event falls into the same category.

Two readings exist side by side. For some scholars, any entry connected with interest falls within the scope of the hadith, which makes an accounting post in a conventional bank problematic, and arguably in any company that carries debt. For others, recording a fact that has already happened is not the same as drafting the contract: the accountant observes and reports the transaction but does not create it. This second reading is widely accepted for businesses whose main activity is lawful.

It depends on the employer

Conventional bank or credit institution

Here the accounting work mostly concerns interest-bearing transactions, which are the core of the business. Many scholars consider these roles very close to the figure of the scribe. The wider context is explained on our page about working in conventional banking and riba.

Lawful business using conventional finance

A manufacturing SME that repays a bank loan or keeps its cash in an interest-bearing account generates incidental interest entries. Most scholars do not blame the accountant for recording them, since the main activity is lawful and the entry does not create the contract.

Business with mixed activities

A group that earns part of its turnover from alcohol or gambling raises an intermediate question. A method for assessing such a role is set out on the page about employers with mixed activities.

Professional duty comes before peace of mind

One point deserves emphasis: an accountant may not, for religious reasons, leave out or disguise an entry. Accounting standards require a true and fair view of the company's position. Failing to record interest that is genuinely payable or receivable would amount to falsification, contrary both to the law and to Islamic ethics, which firmly condemns deception. The risks of going down that road are covered on our page about fraud and corruption at work.

If your conscience does not allow you to record certain transactions, the answer is to change role or employer, never to keep inaccurate books.

Income purification: a sought-after skill

Islamic finance has developed the concept of purification (tathir): when a company or fund receives a share of non-compliant income, that amount is calculated and given to charity, so that the entity does not benefit from it. AAOIFI standards govern this method, particularly for equity screening.

For an accountant, this opens up a whole field of expertise:

• identifying interest income and non-compliant activities in the accounts;
• calculating the purification ratio according to the methodology adopted by the Sharia board;
• documenting charitable donations and making them auditable;
• supporting a company that wants to reduce its interest-bearing financing step by step.

Roles where these skills are valued

Islamic banks and Islamic windows, Islamic fund managers, takaful companies and Sharia audit firms recruit accounting profiles trained in AAOIFI standards and, depending on the country, in the prudential standards of the IFSB. Our page on careers in Islamic finance describes these opportunities, and the one devoted to Islamic finance consulting presents advisory assignments.

In the United Kingdom, the major professional bodies for accountants also set ethical codes that stress integrity and objectivity, values that sit comfortably with the approach described here.

Practical advice

1. Work out which part of your job relates directly to interest-bearing transactions.
2. Favour employers whose main activity is lawful.
3. Never compromise the accuracy of the accounts for reasons of conscience.
4. Train in Islamic accounting to broaden your options.
5. Explain your situation to a scholar who is knowledgeable about financial transactions.

Accounting and ethics are not at odds: the rigour, transparency and honesty that the profession demands are also values that Islam ranks among the highest.
