But when ye divorce women, and the time for sending them away is come, either retain them with generosity, or put them away with generosity: but retain them not by constraint so as to be unjust towards them. He who doth so, doth in fact injure himself. And make not the signs of God a jest; but remember God's favour toward you, and the Book and the Wisdom which He hath sent down to you for your warning, and fear God, and know that God's knowledge embraceth everything.
