Those of your women who commit fornication, let four (Muslim) witness testify to their act. If there is sufficient testimony, confine them to their homes until they die, or until God provides a way for their freedom. 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 Undoubtedly the repentance which Allah has by His grace made obligatory upon Himself to accept, is only the repentance of those who commit sin in folly and then soon repent – towards them does Allah incline in mercy; and Allah is the All Knowing, the 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 Believers! It is not lawful for you to become heirs to women against their will. It is not lawful that you should put constraint upon them that you may take away anything of what you have given them; (you may not put constraint upon them) unless they are guilty of brazenly immoral conduct. Live with your wives in a good manner. If you dislike them in any manner, it may be that you dislike something in which Allah has placed much good for you. 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 can you take it away after each one has enjoyed the other, and they have taken a firm covenant from you? 21 And do not marry those [women] whom your fathers married, except what has already occurred. Indeed, it was an immorality and hateful [to Allah] and was evil as a way. 22
