The ruling on taking zakah from the descendants of the Prophet (peace and blessings be upon him)

Question : Now, some tribes claim descent from the lineage of the Prophet (peace and blessings be upon him). If such people take zakah out of ignorance, not knowing that it is not permissible for them, and then it becomes clear to them, are they liable to guarantee what they took from the prophets?

Answer : First, there is no khums (fifth) in this. If they are poor, we hold that zakah is permissible for them. According to this view, there is no issue. As for the second view, which states that it is not permissible at all, they must return what they took. It has many supporting narrations, but it is a weak opinion, so there is no need to strain to answer it. Yes.
