Wa laa taqtulun nafsal latee harramal laahu illaa bilhaqq; wa man qutila mazlooman faqad ja'alnaa liwaliyyihee sultaanan falaa yusrif fil qatli innahoo kaana mansooraa
(ix) Do not kill any person whom Allah has forbidden to kill, except with right. We have granted the heir of him who has been wrongfully killed the authority to (claim retribution); so let him not exceed in slaying. He shall be helped.
