When you said to him who had been favoured by God and was favoured by you : " Keep your wife to yourself and fear God , " you were hiding something God was about to bring to light , for you had fear of men , though you should fear God more . And when Zaid was through with her , We gave her to you in marriage , so that it may not remain a sin for the faithful ( to marry ) the wives of their adopted sons when they are through with them .
