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 If two (men) among you are guilty of such acts then punish both of them. But if they repent and reform, let them be, for God accepts repentance and is 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 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 And if ye wish to exchange one wife for another and ye have given unto one of them a sum of money (however great), take nothing from it. Would ye take it by the way of calumny and open wrong? 20 And how could you take it away after you have given yourselves to one another, and she has received a most solemn pledge from you? 21 And marry not woman whom your fathers married, except what has already passed; this surely is indecent and hateful, and it is an evil way. 22
