And let those who do not find the means to marry keep chaste until Allah makes them free from want out of His grace . And ( as for ) those who ask for a writing from among those whom your right hands possess , give them the writing if you know any good in them , and give them of the wealth of Allah which He has given you ; and do not compel your slave girls to prostitution , when they desire to keep chaste , in order to seek the frail good of this world 's life ; and whoever compels them , then surely after their compulsion Allah is Forgiving , Merciful .
