No affliction can befall man but by God's permission -- He guides the hearts of those who believe in Him: God has knowledge of all things -- 11 Obey God and the Messenger, but if you turn away, know that the only duty of Our Messenger is to clearly preach. 12 God is the only Lord and in Him the believers should trust. 13 O ye who believe! verily of your wives and your children there is an enemy unto you; wherefore beware of them. And if ye pardon and pass over and forgive, then verily Allah is Forgiving, Merciful. 14 Your wealth and your children are but a trial, and Allah has with Him a great reward. 15 So keep your duty to Allah as best ye can, and listen, and obey, and spend; that is better for your souls. And whoso is saved from his own greed, such are the successful. 16 If you lend a goodly loan to God, He will double it for you, and forgive you. God knows the worth of good deeds and is clement, 17 The knower of the unknown and the known, all-mighty and all-wise. 18
