Is the death penalty waived for a murdering father if one of the victim's children forgives him, and what is the way to waive the ruling? Is it preferable to apply the ruling or for there to be repentance after forgiveness from the victim's guardians? Is it permissible to perform Hajj on behalf of a deceased father who had debts? Does attempting to persuade the victim's guardians to forgive constitute an impediment to the application of one of Allah's prescribed penalties?

Intentional killing is one of the major sins. If the killer repents with sincere repentance, Allah's right is waived, but the right of the victim and their guardians remains. The guardians' right is waived through retribution (Qisas), blood money (Diyya), or forgiveness.

It is permissible to seek forgiveness from the victim's guardians, who are their heirs. If one of the guardians forgives retribution or accepts blood money, retribution is waived. If one of the heirs is a minor, it is necessary to wait until they reach maturity and make their choice.

Children should encourage their parents to repent from killing. It is an act of filial piety to pay off their debts from their estate after their death if they do not have money, as this takes precedence over performing Hajj on their behalf.
