NO CALAMITY can ever befall [man] unless it be by God's leave: hence, whoever believes in God guides his [own] heart [towards this truth]; and God has full knowledge of everything. 11 And obey God, and obey the Messenger; but if you turn your backs, it is only for the Messenger to deliver the Manifest Message. 12 God is the only Lord and in Him the believers should trust. 13 O believers, among your wives and children there is an enemy to you; so beware of them. But if you pardon, and overlook, and if you forgive, surely God is All-forgiving, All-compassionate. 14 Your possessions and your children are only a trial, and Allah it is with Whom is a great reward. 15 so be mindful of God as best as you can; and listen, and obey; and spend in charity: it is for your own good. Those who guard themselves against their own greed will surely prosper: 16 if you give a good loan to God, He will multiply it for you and forgive you, for God is appreciative and forbearing; 17 Knower He of the Unseen and the Visible, the All-mighty, the All-wise. 18
