It is not for a believer to slay another believer unless by mistake. And he who has slain a believer by mistake, his atonement is to set free from bondage a believing person and to pay blood-money to his heirs, unless they forgo it by way of charity. And if the slain belonged to a hostile people, but was a believer, then the atonement is to set free from bondage a believing person. And if the slain belonged to a (non-Muslim) people with whom you have a covenant, then the atonement is to pay the blood-money to his heirs, and to set free from bondage a believing person. But he who cannot (free a slave) should fast for two consecutive months. This is the penance ordained by Allah. Allah is All-Knowing, All-Wise. 92 If anyone kills a believer deliberately, his reward shall be eternal Hell. God will condemn him and reject him, and prepare for him a terrible punishment. 93 Believers! When you go forth in the way of Allah, discern (between friend and foe), and do not say to him who offers you the greeting of peace: 'You are not a believer.' If you seek the good of this worldly life, there lies with Allah abundant gain. After all, you too were such before, and then Allah was gracious to you. Discern, then, for Allah is well aware of what you do. 94 Those of the believers who sit still, other than those who have a (disabling) hurt, are not on an equality with those who strive in the way of Allah with their wealth and lives. Allah hath conferred on those who strive with their wealth and lives a rank above the sedentary. Unto each Allah hath promised good, but He hath bestowed on those who strive a great reward above the sedentary; 95 Degrees [of high position] from Him and forgiveness and mercy. And Allah is ever Forgiving and Merciful. 96
