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 the two persons (man and woman) among you who commit illegal sexual intercourse, punish them both. And if they repent (promise Allah that they will never repeat, i.e. commit illegal sexual intercourse and other similar sins) and do righteous good deeds, leave them alone. Surely, Allah is Ever the One Who accepts repentance, (and He is) Most Merciful. 16 But God undertakes to accept repentance only from those who do evil out of ignorance and those who repent soon after. God turns towards such people with mercy; He 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 Believers, it is not lawful for you to inherit women against their will, nor should you detain them wrongfully, so that you may take away a part of what you have given them, unless they are guilty of something clearly outrageous. Live with them in accordance with what is fair and kind; if you dislike them, it may be that you dislike something which God might 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 And do not marry women that your fathers married, unless it be a thing of the past; surely that is indecent and hateful; an evil way. 22
