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 as for the two of you who are guilty thereof, punish them both. And if they repent and improve, then let them be. Lo! Allah is ever relenting, 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 But (He does not accept) the repentance of those who continue indulging in evil until death draws near and they say: "We now repent;" nor of those who die disbelieving. For them We have a grievous retribution in wait. 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 And how will you take it back whereas you have become unveiled before each other, and they have taken a strong 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
