Quran 4:130 — Women (Al-Nesa')

If the couple must decide to part, GOD will provide for each of them from His bounties. GOD is Bounteous, Most Wise.

[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.

[4:131] To GOD belongs everything in the heavens and the earth, and we have enjoined on those who received the scripture before you, and enjoined on you, that you shall reverence GOD. If you disbelieve, then to GOD belongs everything in the heavens and the earth. GOD is in no need, Praiseworthy.
