Never should a believer kill a believer; but (If it so happens) by mistake, (Compensation is due): If one (so) kills a believer, it is ordained that he should free a believing slave, and pay compensation to the deceased's family, unless they remit it freely. If the deceased belonged to a people at war with you, and he was a believer, the freeing of a believing slave (Is enough). If he belonged to a people with whom ye have treaty of Mutual alliance, compensation should be paid to his family, and a believing slave be freed. For those who find this beyond their means, (is prescribed) a fast for two months running: by way of repentance to Allah: for Allah hath all knowledge and all wisdom.

It was not fitting for the people of Medina and the Bedouin Arabs of the neighbourhood, to refuse to follow Allah's Messenger, nor to prefer their own lives to his: because nothing could they suffer or do, but was reckoned to their credit as a deed of righteousness,- whether they suffered thirst, or fatigue, or hunger, in the cause of Allah, or trod paths to raise the ire of the Unbelievers, or received any injury whatever from an enemy: for Allah suffereth not the reward to be lost of those who do good;-

信士不致于杀害信士，除非是误杀。谁误杀一个信士，谁当释放一个信道的奴隶，并以血锾交付尸亲，除非他们自愿让与。被杀的信士，如果他的宗族是你们的敌人，那末，凶手应当释放一个信道的奴隶。 如果被杀者的宗族是你们的盟友，那末，凶手应当以血锾交付尸亲，并释放一个信道的奴隶。谁不能释放奴隶，谁当边续斋戒两月，这是因为真主准许他悔过自新。真主是全知的，是至睿的。

麦地那人和他们四周的游牧的阿拉伯人，不该逗留在后方，而不随使者出征；不该只顾自己的安逸，而不与使者共患难。因为凡他们为真主而遭遇的饥渴和劳顿，他们触怒不信道者的每一步伐，或每次对敌人有所获，每有一件就必为他们记一功，真主一定不使行善者徒劳无酬。
