Obligation of a killer's family paying Diyah in involuntary manslaughter and quasi-deliberate homicide

A: The ruling that the killer's family should pay the Diyah applies to involuntary manslaughter and quasi-deliberate homicide. As for premeditated murder, the killer's family should not pay any part of the Diyah, as it is to be paid by the killer only. However, there is no problem if the members of the family agree to help him to pay the Diyah.May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
