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 whereas repentance shall not be accepted from those who do evil deeds until their dying hour and then say: "Behold, I now repent"; nor from those who die as deniers of the truth: it is these for whom We have readied grievous suffering. 18 Believers! It is not lawful for you to become heirs to women against their will. It is not lawful that you should put constraint upon them that you may take away anything of what you have given them; (you may not put constraint upon them) unless they are guilty of brazenly immoral conduct. Live with your wives in a good manner. If you dislike them in any manner, it may be that you dislike something in which Allah has placed much good for you. 19 And if you wish to change one wife for another and you have given her heaps of treasure, do not take back anything from it; will you take it back by slander and open sin? 20 And how could ye take it when ye have gone in unto each other, and they have Taken from you a solemn covenant? 21 And do not marry those [women] whom your fathers married, except what has already occurred. Indeed, it was an immorality and hateful [to Allah] and was evil as a way. 22
