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 Obey God and the Messenger, but if you turn away, know that the only duty of Our Messenger is to clearly preach. 12 Allah! there is no God but He! In Allah, therefore, let the believers put their trust. 13 O ye who believe! Lo! among your wives and your children there are enemies for you, therefor beware of them. And if ye efface and overlook and forgive, then lo! Allah is Forgiving, Merciful. 14 Your wealth and your children are just a test; and with Allah is a tremendous reward. 15 So fear God as far as you are able, and give ear, and obey, and expend well for yourselves. And whosoever is guarded against the avarice of his own soul, those -- they are the prosperers. 16 If you loan Allah a goodly loan, He will multiply it for you and forgive you. And Allah is Most Appreciative and Forbearing. 17 The Knower of the unseen and the seen, the Mighty, the Wise. 18
