Those who commit unlawful sexual intercourse of your women - bring against them four [witnesses] from among you. And if they testify, confine the guilty women to houses until death takes them or Allah ordains for them [another] way. 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 Of no effect is the repentance of those who continue to do evil, until death faces one of them, and he says, "Now have I repented indeed;" nor of those who die rejecting Faith: for them have We prepared a punishment most grievous. 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 But if you want to replace one wife with another and you have given one of them a great amount [in gifts], do not take [back] from it anything. Would you take it in injustice and manifest sin? 20 How could you do that having slept with one another, and when they had taken a solemn pledge from you? 21 Do not marry women whom your fathers married, except for what has already taken place in the past. This is indeed a shameful deed, a loathsome thing and an evil practice. 22
