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 And she in whose house he was, solicited him against himself; and she fastened the doors, and said: come on, O thou! He said: Allah be my refuge: verily he is my lord; he hath made me a goodly dwelling; verily the wrong-doers fare not well. 23 She verily desired him, and he would have desired her if it had not been that he saw the argument of his Lord. Thus it was, that We might ward off from him evil and lewdness. Lo! he was of Our chosen slaves. 24 Both of them raced to the door, and she (grabbed and) rent his shirt from behind. They met her lord outside the door. "There is no other penalty for a man," said she, "who wanted to outrage your wife but imprisonment or grievous punishment." 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 it is torn from behind then she is lying, and he speaks the truth." 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 Ignore this affair, O Joseph; and you, O woman, ask forgiveness for your sin, for you were surely errant." 29
