Quran 4:18 — Women (Al-Nesa')

Not acceptable is the repentance of those who commit sins until death comes to them, then say, "Now I repent." Nor is it acceptable from those who die as disbelievers. For these, we have prepared a painful retribution.

[4:17] Repentance is acceptable by GOD from those who fall in sin out of ignorance, then repent immediately thereafter. GOD redeems them. GOD is Omniscient, Most Wise.

[4:19] O you who believe, it is not lawful for you to inherit what the women leave behind, against their will. You shall not force them to give up anything you had given them, unless they commit a proven adultery. You shall treat them nicely. If you dislike them, you may dislike something wherein GOD has placed a lot of good.
