What is the ruling on money (one thousand dirhams) paid by an interest-based bank to a student at the end of his studies, knowing that the student did not deal directly with the bank?

What the usurious bank pays out falls into two categories:

1. If it is from the very essence of usury (usurious interest): It is not permissible to take it unless you are poor, in which case it is spent on the poor and charitable causes as a way of disposing of it. 2. If it is not from the very essence of usurious interest, but rather from the bank's funds obtained from permissible projects: There is no harm in taking it, even though there is a difference of opinion among scholars regarding accepting a gift from someone whose lawful and unlawful wealth is mixed. Al-Hasan, Mak'hul, Al-Zuhri, and Al-Shafi'i (though Al-Shafi'i disliked it) permitted it, while Ibn Al-Musayyib, Al-Qasim ibn Muhammad, Al-Thawri, Ahmad, and others disliked it.

It is advisable not to take it if there is doubt as to whether it is from usurious interest and the inquirer is in a comfortable financial situation, in accordance with the hadith: "Whoever guards against doubtful matters has indeed acquitted himself with regard to his religion and his honor."
