There is no blame on you if you divorce women when you have not touched them or appointed for them a portion, and make provision for them, the wealthy according to his means and the straitened in circumstances according to his means, a provision according to usage; (this is) a duty on the doers of good (to others).

And all married women except those whom your right hands possess (this is) Allah's ordinance to you, and lawful for you are (all women) besides those, provided that you seek (them) with your property, taking (them) in marriage not committing fornication. Then as to those whom you profit by, give them their dowries as appointed; and there is no blame on you about what you mutually agree after what is appointed; surely Allah is Knowing, Wise.
