What is the ruling on the blood money for accidental killing if the killer's 'aqilah (male relatives) are unable to pay it due to poverty or scarcity, and is it permissible for the victim's family to waive it?

If the 'Aqilah' (group responsible for paying blood money) is unable to pay the blood money due to poverty or insufficient numbers, the Bayt al-Mal (public treasury) should pay it.

The victim's family can also pardon the killer and waive the blood money, as it is a private right belonging to them. Allah Almighty says: "But whoever chooses to remit it, it shall be an expiation for him" (Al-Ma'idah: 45).
