He who disbelieves in Allah after his having believed, not he who is compelled while his heart is at rest on account of faith, but he who opens (his) breast to disbelief-- on these is the wrath of Allah, and they shall have a grievous chastisement.

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.
