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 as for those twain of you who commit it, hurt them both; then, if they repent and amend, turn away from them; verily Allah is Relenting, Merciful. 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 And of no effect is the repentance of those who continue to do evil deeds until death faces one of them and he says: "Now I repent;" nor of those who die while they are disbelievers. For them We have prepared a painful torment. 18 O YOU who have attained to faith! It is not lawful for you to [try to] become heirs to your wives [by holding onto them] against their will; and neither shall you keep them under constraint with a view to taking away anything of what you may have given them, unless it be that they have become guilty, in an obvious manner, of immoral conduct. And consort with your wives in a goodly manner; for if you dislike them, it may well be that you dislike something which God might yet make a source of abundant good. 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 How can you take it back when you have had intimate relations and made a solemn agreement with each other? 21 Do not marry women whom your fathers married, except for what has already taken place in the past. This is indeed a shameful deed, a loathsome thing and an evil practice. 22
