The family of the deceased claiming Qisas in front of the ruler

Q 2: Is it permissible for the husband to demand Qisas (just retaliation) for the murderer of his wife?

A: Demanding Qisas (just retaliation) at the ruler from the criminal is the right of the heirs of a murdered person and the husband is one of those who have the right to demand Qisas for the wife unless he is denied inheritance for some legal causes.May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his Family, and Companions.
