Let those who cannot find someone to marry maintain chastity until God makes them rich through His favors. Let the slaves who want to buy their freedom have an agreement with you in writing if you find them to be virtuous. Give them money out of God's property which He has given to you. Do not force your girls into prostitution to make money if they want to be chaste. If they have been compelled to do so, God will be All-merciful and All-forgiving to them.
