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 If two men among you are guilty of lewdness, punish them both. If they repent and amend, Leave them alone; for Allah is Oft-returning, Most Merciful. 16 Allah accept the repentance of those who do evil in ignorance and repent soon afterwards; to them will Allah turn in mercy: For Allah is full of knowledge and wisdom. 17 But of no avail is repentance of those who do evil until death approaches any one of them and then he says: 'Now I repent.' Nor is the repentance of those who die in the state of unbelief of any avail to them. For them We have kept in readiness a painful chastisement. 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 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 can ye take it back when one of you hath gone in unto the other, and they have obtained from you a rigid bond! 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
