And when you divorce women and they reach their prescribed time, then either retain them in good fellowship or set them free with liberality, and do not retain them for injury, so that you exceed the limits, and whoever does this, he indeed is unjust to his own soul; and do not take Allah's communications for a mockery, and remember the favor of Allah upon you, and that which He has revealed to you of the Book and the Wisdom, admonishing you thereby; and be careful (of your duty to) Allah, and know that Allah is the Knower of all things.

So when harm afflicts a man he calls upon Us; then, when We give him a favor from Us, he says: I have been given it only by means of knowledge. Nay, it is a trial, but most of them do not know.
