And let those who cannot find a match keep chaste until Allah gives them means from His grace. And if any of your slaves asks for a Deed in writing (an agreement to purchase their freedom), write it for them if you know any good in them; yea, give them something yourselves from out of the wealth Allah has given you. But force not your slave girls to prostitution when they desire chastity, in order to make a gain in goods of this world. But if any one compels them, then, after they are compelled, verily, Allah will be to them (the slave girls) Forgiving, Merciful.
