Is blood money and expiation obligatory for someone who hit a person with his car as a result of the latter's sudden appearance and his inability to avoid the accident except by endangering his own life, knowing that he does not possess sufficient funds for blood money and cannot seek assistance from his 'Aqilah (male relatives responsible for paying blood money), and is it permissible for him to pay what he possesses even if it affects his ability to help his children marry, or is it sufficient for him to pay the insurance amount?

The blood money (diyya) for accidental killing is borne by the killer's 'aqila (male relatives on the father's side). The killer is not required to bear more than any single member of his 'aqila. If the 'aqila refuse to pay it, then they have refused a right enjoined upon them by Allah. If another party, such as an insurance company, undertakes to pay the blood money, it is permissible for the victim's guardian to accept it, and the claim for it is dropped. The killer must also pay expiation (kaffara), which is the freeing of a believing slave; if he cannot find one, then he must fast for two consecutive months. It must be emphasized that a person is not allowed to avert the danger of death from himself at the expense of another person's life.
