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 And she in whose house he was sought to make himself yield (to her), and she made fast the doors and said: Come forward. He said: I seek Allah's refuge, surely my Lord made good my abode: Surely the unjust 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 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! Said she: "What ought to be the punishment of one who had evil designs on [the virtue of] thy wife - [what] but imprisonment or a [yet more] grievous chastisement?" 25 Said Yusuf, “It was she who lured me, that I may not guard myself” – and a witness from her own household testified; “If his shirt is torn from the front, then the woman is truthful and he has spoken incorrectly.” 26 But if his shirt is torn from behind, then she has lied, and he is truthful." 27 When he saw his shirt was torn from behind he said, 'This is of your women's guile; surely your guile is great. 28 Joseph, turn away from this. And you, ask forgiveness for your sin. You are indeed one of the sinners' 29
