24:33
And let be chaste those who (do) not find (means for) marriage until enriches them Allah from His Bounty. And those who seek the writing from (those) whom possess your right hands, then give them (the) writing if you know in them any good and give them from the wealth (of) Allah which He has given you. And (do) not compel your slave girls to [the] prostitution, if they desire chastity that you may seek temporary gain (of) the life (of) the world. And whoever compels them, then indeed, Allah from after their compulsion (is) Oft-Forgiving, Most Merciful.
