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 (And remember that) Allah's acceptance of repentance is only for those who commit evil out of ignorance and then soon repent. It is towards such persons that Allah turns graciously. Allah is All-Knowing, All-Wise. 17 There is no forgiveness for those who commit sin and do not repent until the last moment of their lives nor for those who die as unbelievers. For these people We have prepared a painful torment. 18 O YOU who have attained to faith! It is not lawful for you to [try to] become heirs to your wives [by holding onto them] against their will; and neither shall you keep them under constraint with a view to taking away anything of what you may have given them, unless it be that they have become guilty, in an obvious manner, of immoral conduct. And consort with your wives in a goodly manner; for if you dislike them, it may well be that you dislike something which God might yet make a source of abundant good. 19 If you wish to take a wife in the place of another wife, and you have given to one a Qintar (about 100000 lb) so do not take from it anything. What, will you take it by way of calumny and a clear sin! 20 How can you take it when you have been intimate with one another, and she has taken a solemn pledge from you? 21 And marry not women whom your fathers married, except what has already passed; indeed it was shameful and most hateful, and an evil way. 22
