The king said: "Bring this man to me." But when the royal messenger came to Joseph he said: "Go back to your master and ask him about the case of the women who had cut their hands. Surely my Lord has full knowledge of their guile." 50 He (the king) (then sent for those women and) said: What happened when ye asked an evil act of Joseph? They answered: Allah Blameless! We know no evil of him. Said the wife of the ruler: Now the truth is out. I asked of him an evil act, and he is surely of the truthful. 51 [When Joseph learned what had happened, he said: "I asked for] this, so that [my former master] might know that I did not betray him behind his back, and that God does not bless with His guidance the artful schemes of those who betray their trust. 52 ۞ And I do not declare myself free, most surely (man's) self is wont to command (him to do) evil, except such as my Lord has had mercy on, surely my Lord is Forgiving, Merciful. 53 The king said, 'Bring him to me! I would attach him to my person.' Then, when he had spoken with him, he said, 'Today thou art established firmly in our favour and in our trust.' 54 He said: set me over the store houses of the land; verily I shall be a keeper knowing. 55 And thus did We give to Yusuf power in the land-- he had mastery in it wherever he liked; We send down Our mercy on whom We please, and We do not waste the reward of those who do good. 56 But verily the reward of the Hereafter is the best, for those who believe, and are constant in righteousness. 57
