The duty of the people of hisbah toward those who deal in riba

Question:
What is the duty of the people of hisbah toward those who deal in riba? And how are those riba-dealers to be disciplined, given that they are committing major sins? Is it sufficient to merely dislike them? Please inform us, may Allah reward you. May Allah reward you with good.

Answer:
The people of hisbah and those other than them are required to offer advice. They must offer advice to the people of sins. Whoever knows the one in question should advise him if they are able. As for discipline and punishment, that is the responsibility of the rulers of the community. They are the ones who bring them to trial and punish them with what is prescribed. The one who owes a pilgrimage is punished by performing the pilgrimage, and the one who requires discipline is disciplined accordingly. This is not specific to riba; it applies to zina, backbiting, talebearing, rights of parents, and severing family ties, among other things that we know of.
