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 when two of you commit indecency, punish them both; but if they repent and make amends, then suffer them to be; God turns, and is All-compassionate. 16 God does accept repentance, but only of those who are guilty of an evil out of ignorance yet quickly repent, and God turns to them again, for God is all-knowing and all-wise. 17 But (He does not accept) the repentance of those who continue indulging in evil until death draws near and they say: "We now repent;" nor of those who die disbelieving. For them We have a grievous retribution in wait. 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 And if ye wish to exchange one wife for another and ye have given unto one of them a sum of money (however great), take nothing from it. Would ye take it by the way of calumny and open wrong? 20 And how could you take it away after you have given yourselves to one another, and she has received a most solemn pledge from you? 21 Do not marry, from now on, the ex-wives of your fathers for that custom was sinful, loathsome, and abominable. 22
