And the man from Egypt who bought him said to his wife: "Make his stay [with us] honourable; he may well be of use to us, or we may adopt him as a son. And thus We gave unto Joseph a firm place on earth; and [We did this] so that We might impart unto him some understanding of the inner meaning of happenings. For, God always prevails in whatever be His purpose: but most people know it not. 21 When he reached the prime of life We gave him wisdom and knowledge. Thus We reward those who are good. 22 But she in whose house he resided wished to seduce him and, closing the doors, said: "Come into me. "God forbid!" he said; "he is my master who has approved my stay. Surely those who act wrongly do not prosper." 23 And indeed she did desire him and he would have inclined to her desire, had he not seen the evidence of his Lord. Thus it was, that We might turn away from him evil and illegal sexual intercourse. Surely, he was one of Our chosen, guided slaves. 24 So they both raced each other to the door, and she tore his shirt from the back: they both found her lord near the door. She said: "What is the (fitting) punishment for one who formed an evil design against thy wife, but prison or a grievous chastisement?" 25 He said: "It was she that sought to seduce me - from my (true) self." And one of her household saw (this) and bore witness, (thus):- "If it be that his shirt is rent from the front, then is her tale true, and he is a liar! 26 but, if his shirt is torn from behind, she lied, and he is of the truthful' 27 When the master saw that Joseph's shirt was torn from behind, he told his wife, "This is some of your womanly guile in which you are certainly skillful. 28 [But,] Joseph, let this pass! And thou, [O wife,] ask forgiveness for thy sin - for, verily, thou hast been greatly at fault!" 29
