Is the money a husband receives as a bonus for opening a line of credit for the company in banks that deal with usury permissible or forbidden?

The action of the husband in opening a line of credit for his employer with banks and receiving a commission in return is subject to detailed explanation:

- If the dealings are with Islamic banks and within Shariah-compliant regulations, then there is no harm in this, nor in the commission. The fact that Islamic banks are affiliated with the Central Bank does not affect this.

- However, if the procedures are with a usurious bank, then this is not permissible for him, and the commission is not lawful for him; this is based on the words of Allah Almighty: "And cooperate in righteousness and piety, but do not cooperate in sin and aggression" [Al-Ma'idah: 2], and due to the Prophet's (peace be upon him) prohibition of dealing with usury.
