If any of your women is guilty of unnatural offence, bring four of your witnesses to give evidence; if they testify against them, retain them in the houses until death overtakes them or God provides some other way for them. 15 And punish [thus] both of the guilty parties; but if they both repent and mend their ways, leave them alone: for, behold, God is an acceptor of repentance, a dispenser of grace. 16 (And remember that) Allah's acceptance of repentance is only for those who commit evil out of ignorance and then soon repent. It is towards such persons that Allah turns graciously. Allah is All-Knowing, All-Wise. 17 And repentance is not for those who go on working evil until when death presenteth itself unto one of them, and he saith: verily now I repent; nor for those who die while they are infidel. These! for them We have gotten ready a torment afflictive. 18 O you who believe! it is not lawful for you that you should take women as heritage against (their) will, and do not straiten them in order that you may take part of what you have given them, unless they are guilty of manifest indecency, and treat them kindly; then if you hate them, it may be that you dislike a thing while Allah has placed abundant good in it. 19 If you want to divorce a woman so that you can marry another, do not take back the dowry which you had paid even if what you paid was a large amount of gold. To do this is a slanderous act and a manifest sin. 20 And how could you take it (back) while you have gone in unto each other, and they have taken from you a firm and strong covenant? 21 And do not marry women your fathers married unless it is a thing of the past; surely that was an indecency, hated, and a way of evil. 22
