Those of your women who commit fornication, let four (Muslim) witness testify to their act. If there is sufficient testimony, confine them to their homes until they die, or until God provides a way for their freedom. 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 does accept repentance, but only of those who are guilty of an evil out of ignorance yet quickly repent, and God turns to them again, for God 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 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 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 you take it while you have gone in unto each other and they have taken from you a solemn covenant? 21 And do not marry the women who were wedded to your fathers (and grand fathers), except what has already passed; that is indeed an act of shame and great wrong; and an evil way. 22
