and do not kill anyone whose killing allah has forbidden except for a just cause. and whoever is killed wrongfully we have given his heir the authority. but let him not exceed limits in the matter of taking life. verily he is helped.
ولا تقتلوا النفس التي حرم الله إلا بالحق ومن قتل مظلوما فقد جعلنا لوليه سلطانا فلا يسرف في القتل إنه كان منصورا
