Let those who cannot afford to marry live in continence until God shall enrich them from His own bounty. As for those of your slaves who wish to buy their liberty, free them if you find in them any promise and bestow on them a part of the riches which God has given you. You shall not force your slave-girls into prostitution in order that you may enrich yourselves, if they wish to preserve their chastity. If anyone compels them, God will be forgiving and merciful to them.
