What is the ruling on working for a company that relies for a portion of its profits on usury, while the larger portion of its profits is based on non-usurious transactions, and is it permissible to benefit from the money earned from it during the period of the obligatory contract?

If the platform allows overdrafts with the condition of an increase on the withdrawn amount, this is usury (riba), which is unlawful in Islamic law and considered one of the major sins. This is based on what Muslim narrated from Jabir (may Allah be pleased with him) that the Prophet (peace be upon him) cursed the one who consumes usury, the one who feeds it, its scribe, and its two witnesses. Jurists explained this by the concept of aiding in sin.

It is not permissible to work for the platform if the work is connected to the prohibited part. However, if it is in an area that does not aid in the prohibited, then there is no harm. If the salary was received before knowing about the prohibition, then there is no harm in it. As for what was received after knowing about the prohibition, it must be disposed of by giving it to the poor and needy.

It should be known that these platforms may include other prohibited transactions such as margin trading, or allowing trading with a balance from the platform in exchange for a commission, due to the combination of a loan and brokerage in such cases, as well as dealing in contracts for difference, options, and futures.
