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 reached maturity, We bestowed on him right judgement and knowledge. Thus We reward those who do 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 she advanced towards him, and had Joseph not perceived a sign from his Lord he too would have advanced towards her. Thus was Joseph shown a sign from his Lord that We might avert from him all evil and indecency, for indeed he was one of Our chosen servants. 24 They raced to the door and she tore his shirt from behind. And by the door, they met her husband whereupon she said: 'What is the recompense of one whose intent is evil against your people other than being imprisoned, or sternly punished' 25 (Joseph) said: "It was she who wanted to seduce me." And a witness from her family testified: "If the shirt is torn from the front then the woman is speaking the truth, and he is a liar. 26 And if his shirt is rent from behind, she tells a lie and he is one of the truthful. 27 And when [her husband] saw that his tunic was torn from behind, he said: "Behold, this is [an instance] of your guile, O womankind! Verily, awesome is your guile! 28 O Joseph! Turn away from this, and thou, (O woman), ask forgiveness for thy sin. Lo! thou art of the faulty. 29
