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 With Allah is the repentance of those alone who do an evil foolishly and thereafter repent speedily, surely it is they unto whom Allah shall relent. And Allah is Knowing, Wise. 17 And repentance is not for those who go on doing evil deeds, until when death comes to one of them, he says: Surely now I repent; nor (for) those who die while they are unbelievers. These are they for whom We have prepared a painful chastisement. 18 O Ye who believe! it is not allowed unto you that ye may heir the women forcibly; nor shut them up that ye may take away from them part of that which ye had given them, except when they be guilty of manifest enormity. And live with them reputably; if ye detest them, belike ye detest a thing and yet Allah hath placed therein abundant good. 19 And if you desire to exchange a wife in place of another, and you have given to one a hundredweight, take of it nothing. What, will you take it by way of calumny and manifest 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
