Original idea from here. My question is, is it halal to loan out money which people save in your bank? Let's say we have an online website. People can 'lend' money to the website (no interest), and then the website acts as an agent which lends out that money to people who need it. THe website would also run on charity insha-Allah. Is it halal? What worries me is 'selling things you don't own' and because it deals in currencies (my knowledge of Islamic rulings on currency and trade is quite weak)

JazakAllah Khair!

Fundamentally, yes, it is halal, but considerations must be made on exactly how the "loan" is contracted; attempting to run it like a modern bank where you're handling money that has been deposited (and can be withdrawn at will) would be questionable.

From reading through the proposal in OP's link, two viable scenarios come to mind, both of which are generally considered permissible:

  • Mudarabah: This isn't really a loan, so much as investment in a business. One party (the rabb al-mal, in this case the "lender") provides the capital, while the second party (the mudarib, in this case the "bank") would actually run the business. The capital can be worked with in any manner stipulated by the business contract: As long as the contract permits it, then the mudarib may invest or lend out the capital on behalf of the rabb al-mal at her discretion.
    • The rabb al-mal would be entitled to a share of any profits (if relevant) earned from the capital; exactly how the profits would be distributed would be included in the original contract.
    • In the case of any loss, it would be deducted from the original capital. The rabb al-mal may end up receiving less than his full investment in return when the contract is dissolved.
  • Bay al-dayn: This is, quite simply, a business loan. The lender provides a certain amount of capital, and the debtor (in this case the "bank") agrees to pay it back at a specified time (literally, this is selling an amount of money now for the same amount of money later). Until that time, the debtor can do with the capital as she sees fit — it's hers, after all; she technically bought it — including but not limited to investing it or lending it to a third party.
    • The lender in this case is not entitled to any profits from the loaned capital.
    • It becomes incumbent on the debtor to repay her debt in full when it becomes due; even if losses were incurred, the lender takes no share thereof.

As long as you're not attempting to work with more money than you actually have available (e.g. fractional reserve banking, which is common among modern banks), the issue of "selling things you don't own" doesn't even come up.


Assalamu alaikum.

People have entrusted you with their money to safeguard, and it would be your responsibility to look after their property. If you lend their property to someone else and are unable to return it, it would be haram, because it is stealing, although unintentional.

It'd be advisable to use the knowledge of someone who has a background in finance and banking. Their input would be invaluable.


If the people depositing their money know that its being lent and there is a risk that they may not receive it back its halal.

This would be a great form of charity from the depositors since the same dollar could be lent out and returned and lent out again multiple times.
