What is the validity of the jurisprudential saying that a father is not killed if he kills his child, but a mother is killed if she kills her child? Does this indicate that a man's sin is forgiven while a woman's sin is not? What is the ruling on someone who raped his daughter, who was not more than five years old, especially in light of the incident of the preacher Faihan Al-Ghamdi, who raped his daughter and then killed her, and was sentenced to pay blood money?

Killing an innocent soul is one of the gravest sins and is forbidden by scholarly consensus. A father killing his child is also forbidden by scholarly consensus. Scholars, however, differed on whether retribution (qisas) should be exacted from the father or not. The correct view is that the mother is like the father in this ruling; she is not killed for her child's death. The fact that qisas is not exacted from the parent does not mean that he or she is without sin. As for a man raping his daughter, i.e., a man committing zina with his daughter, this necessitates the execution of the stoning penalty upon the father if the zina is proven by evidence or confession. However, if it was an act short of zina, there is no prescribed punishment (hadd) for it; rather, it entails discretionary punishment (ta'zir). It is impermissible to accuse a Muslim and impugn their honor without clear evidence.
