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 God shall turn only towards those who do evil in ignorance, then shortly repent; God will return towards those; God is All-knowing, All-wise. 17 The forgiveness is not for those who do ill-deeds until, when death attendeth upon one of them, he saith: Lo! I repent now; nor yet for those who die while they are disbelievers. For such We have prepared a painful doom. 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 desire to replace one wife with another, do not take any part of her dower back: even if you have given her a treasure. Would you take it by slandering her and with manifest sinfulness? 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 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
