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 When he reached the prime of life We gave him wisdom and knowledge. Thus We reward those who are good. 22 And the woman in whose house he was, allured him not to restrain himself and she closed all the doors – and said, “Come! It is you I address!”; he said, “(I seek) The refuge of Allah – indeed the governor is my master – he treats me well; undoubtedly the unjust never prosper.” 23 And indeed, she desired him, and he desired her; [and he would have succumbed] had he not seen [in this temptation] an evidence of his Sustainer's truth: thus [We willed it to be] in order that We might avert from him all evil and all deeds of abomination - for, behold, he was truly one of Our 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 He said: She sought to make me yield (to her); and a witness of her own family bore witness: If his shirt is rent from front, she speaks the truth and he is one of the liars: 26 but if it be that his shirt has been torn from behind, then she has lied, and he is one of the truthful.' 27 So when he saw his shirt rent from behind, he said: Surely it is a guile of you women; surely your guile is great: 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
