92. It is not lawful for a believer to kill a believer except by mistake. Anyone who kills a believer unintentionally shall (be liable to) free a believing slave and blood money (as compensation) to be paid to his family unless they remit it in charity. If he (i.e. the slain) belongs to a people that are hostile to you and is a believer, then (only) the freeing of a believing slave (is the compensation). And if he (i.e. the slain) belongs to a people with whom you have a treaty, then blood money is to be paid to his family along with the freeing of a believing slave. But whoever does not find (the means to pay) should fast for two consecutive months as a means of pardon from Allah. And Allah is All-Knowing, All-Wise.

وما كان لمؤمن أن يقتل مؤمنا إلا خطئا ومن قتل مؤمنا خطئا فتحرير رقبة مؤمنة ودية مسلمة إلى أهله إلا أن يصدقوا فإن كان من قوم عدو لكم وهو مؤمن فتحرير رقبة مؤمنة وإن كان من قوم بينكم وبينهم ميثاق فدية مسلمة إلى أهله وتحرير رقبة مؤمنة فمن لم يجد فصيام شهرين متتابعين توبة من الله وكان الله عليما حكيما
