It is not for a believer to slay a believer except by a mischance; and whosoever slayeth a believer by mischance on him is the setting free of a believing bondman and blood-wit to be delivered to his family except that they forego. Then if he be of a people hostile unto you and is himself a believer, then the setting free of a believing bondman; and if he be of a people between man whom and you is a bond, then the bloodwit to be delivered to his family and the setting free of a believing bondman. Then whosoever findeth not the wherewithal, on him is the fasting for two months in succession: a penance from Allah. And Allah is ever Knowing, Wise.
