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 His master's wife then tried to seduce him.

The unjust will certainly have no happiness." 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 And they both rushed to the door; and she [grasped and] rent his tunic from behind - and [lo!] they met her lord at the door!

"If his shirt is torn from the front, then she has told the truth, and he is of the liars. 26 but if his tunic has been torn from behind, then she is lying, and he is speaking 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 Joseph, pass this over! (O wife), ask forgiveness for thy sin, for truly thou hast been at fault!" 29
