Then they found in it a wall which was on the point of falling, so he put it into a right state. (Musa) said: If you had pleased, you might certainly have taken a recompense for it.

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.
