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 And when he had attained his maturity, We gave him wisdom and knowledge: and thus do We reward those who do good. 22 But she in whose house he was, sought to seduce him from his (true) self: she fastened the doors, and said: "Now come, thou (dear one)!" He said: "Allah forbid! truly (thy husband) is my lord! he made my sojourn agreeable! truly to no good come those who do wrong!" 23 And certainly she made for him, and he would have made for her, were it not that he had seen the manifest evidence of his Lord; thus (it was) that We might turn away from him evil and indecency, surely he was one of Our sincere servants. 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 (Joseph) said: She it was who asked of me an evil act. And a witness of her own folk testified: If his shirt is torn from before, then she speaketh truth and he is of the liars. 26 "But if it be that his shirt is torn from the back, then is she the liar, and he is telling the truth!" 27 And when he saw his shirt torn at the back, he said: 'This is one of your (women's) guiles. Your guile, (O woman), is great indeed! 28 O Yusuf! turn aside from this; and (O my wife)! ask forgiveness for your fault, surely you are one of the wrong-doers. 29
