4:19 Believers, it is unlawful for you to inherit women forcefully, neither bar them, in order that you go off with part of what you have given them, except when they commit a clear indecency. Live with them honorably. If you hate them, it may be that you hate something which Allah has set in it much good.
4:20 If you wish to take a wife in the place of another wife, and you have given to one a Qintar (98,841.6 lbs.) so do not take from it anything. What, will you take it by way of calumny and a clear sin!
