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 If two (men) among you are guilty of such acts then punish both of them. But if they repent and reform, let them be, for God accepts repentance and is merciful. 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 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 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 If you wish to take a wife in the place of another wife, and you have given to one a Qintar (about 100000 lb) so do not take from it anything. What, will you take it by way of calumny and a clear sin! 20 How could you do that having slept with one another, and when they had taken a solemn pledge from you? 21 AND DO NOT marry women whom your fathers have previously married - although what is past is past: this, verily, is a shameful deed, and a hateful thing, and an evil way. 22
