If any of your women commit fornication, call in four male witnesses from among yourselves against them; if they testify to their guilt, confine them to the house until death releases them or until God gives them another way out. 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 (Allah accepts) the repentance from only those who commit evil in ignorance and then quickly turn to Him in repentance. Allah will relent towards them. Allah is Knowing, Wise. 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 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 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 How shall you take it, when each of you has been privily with the other, and they have taken from you a solemn compact? 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
