Can a Muslim work in a conventional bank?

Why the scholars prohibit it

The ruling rests on a hadith in which the Prophet ﷺ extended the curse beyond the one who takes interest to everyone who assists the transaction:

"The Messenger of Allah ﷺ cursed the one who consumes riba, the one who feeds it to others, the one who writes it down, and its two witnesses." And he said: "They are all the same."— Sahih Muslim 1598, from Jabir ibn Abdullah

Al-Nawawi رحمه الله, commenting on this narration, drew out its implication: it is an explicit prohibition of writing the contract of sale between two parties dealing in interest, and of witnessing it, and in it is the prohibition of assisting in falsehood. The scholars then apply the Qur'anic principle:

"And cooperate in righteousness and piety, but do not cooperate in sin and aggression."— Qur'an 5:2

Shaykh Ibn Baz رحمه الله explains that working in an interest-based bank is forbidden because it is cooperation in sin and transgression, and because the bank is, in the words of the fatwa, at war with Allah and His Messenger.

It is not only the interest clerk

A common assumption is that the prohibition applies only to those who sign the interest contracts. The scholars reject this. The Permanent Committee was asked precisely about a man who works in a bank dealing in interest but whose own work is not interest-based, and answered that it is still not permissible — because by his work he provides the bank's other employees with what they need and helps them in their interest-based work.

IslamWeb (fatwa 405526) carries this further: any service an employee performs in an interest-based bank is a supporting function for the work of the others. The same reasoning is applied to the accountant, the auditor, the building's landlord, the guard and the cleaner — all of them, the scholars say, cooperate in keeping the bank's interest-based operation running.

The salary

Because the work is prohibited, the salary earned from it is prohibited too, since it is the product of unlawful work. IslamWeb (fatwa 71225) notes that the presence of some permissible services the bank may offer makes no difference, because the bank's principal business is lending and borrowing at interest, and the ruling follows the predominant activity. The same fatwa directs the reader to a separate ruling for detail on what has already been spent on food, drink, housing and the like.

The exception of necessity

The scholars do allow a genuine exception, and it is narrow. IslamWeb (fatwa 397909) states that if a person is compelled to work in an interest-based bank — finding no other work and no lawful means of earning enough to cover his basic needs — then he may work there out of necessity until he finds another way. IslamWeb (fatwa 405526) puts the same condition: if you find no work other than it to spend on yourself and your family, you may remain in the job while searching for a permissible one, and once you find it you must leave the prohibited work, because necessity is measured by its actual extent.

Two points the scholars stress about this concession:

• It is a temporary permission, not a licence. It lasts only as long as the necessity does, and it carries the obligation to keep looking for lawful work.
• Debt does not by itself create the necessity. IslamWeb (fatwa 115021) was asked about a man in debt and answered that the debts have no bearing on the obligation to leave the bank's work, since an alternative exists through which the debts can be repaid.

If the bank has an Islamic branch

Where a bank combines a conventional and an Islamic system, IslamWeb (fatwa 24967) distinguishes the case: if your work is in the Islamic branch, and that branch is independent in its transactions from the interest-based bank, and you take your salary from the branch, then that is permissible.

In practice

• If you are considering such a job: the ruling is that you should not take it, and you should look for work at an Islamic bank or elsewhere. IslamWeb (fatwa 10274) notes that working in an Islamic bank is permissible when its transactions are governed by the Shari'ah, and that such banks should be encouraged and supported.
• If you are already in one: the scholars' instruction is to leave it and repent, and to be certain that Allah blesses lawful provision however small it is and erases the unlawful however abundant. If you genuinely cannot find other work, the concession above applies while you search.
• If you are only receiving money through such a bank: taking a transfer or your salary that has been routed through an interest-based bank is a different matter from working there. Shaykh 'Abd al-Muhsin al-'Abbad said there is no harm in collecting money that is rightfully yours through a bank, though he advised taking it promptly so the bank cannot use it in interest.

Key takeaways

• Working in a conventional interest-based bank is prohibited, and this is the position of Shaykh Ibn Baz, the Permanent Committee and IslamWeb.
• The prohibition covers every role, including one that does not itself handle interest contracts, because the work supports the bank's interest-based operation.
• The salary from such work is prohibited, since it is the product of prohibited work.
• A genuine necessity — no other work and no lawful means of covering basic needs — permits staying temporarily while actively seeking lawful work.
• Working in an independent Islamic branch of a mixed bank is permissible.
