Quran 4:128 — Women (Al-Nesa')

If a woman senses oppression or desertion from her husband, the couple shall try to reconcile their differences, for conciliation is best for them. Selfishness is a human trait, and if you do good and lead a righteous life, GOD is fully Cognizant of everything you do.

[4:127] They consult you concerning women: say, "GOD enlightens you regarding them, as recited for you in the scripture. You shall restore the rights of orphaned girls whom you cheat out of their due dowries when you wish to marry them: you shall not take advantage of them. The rights of orphaned boys must also be protected as well. You shall treat the orphans equitably. Whatever good you do, GOD is fully aware thereof."

[4:129] You can never be equitable in dealing with more than one wife, no matter how hard you try. Therefore, do not be so biased as to leave one of them hanging (neither enjoying marriage, nor left to marry someone else). If you correct this situation and maintain righteousness, GOD is Forgiver, Most Merciful.
