Reflecting on these verses suggests that she had turned to Joseph's religion, monotheism. His imprisonment was a great turning point in her life.
After this, the Qur'anic style neglects the story of the chief minister's wife completely. We do not know what happened to her after she gave her clear evidence. Yet still, there are legends about her. It has been said that after her husband died she married Joseph, and, behold, she was a virgin. She confessed that her husband had been old and had never touched women. Other legends said that she lost her sight, weeping for Joseph. She abandoned her palace and wandered in the streets of the city.
However, the lady disappeared from the Qur'anic narrative at a suitable stage, at the climax of her trouble. Perhaps she lingers in memory longer than if we had known the ending.
Joseph's High Position
The king informed Joseph that his innocence was established and ordered him to come to the palace for an interview. The king recognized his noble qualities. When Joseph came, the king spoke to him in his tongue. Joseph's replies astonished the king with his cultural refinement and wide knowledge.
Then the conversation turned to the dream. Joseph advised the king to start planning for years of famine ahead. He informed him that the famine would affect not only Egypt but the neighboring countries as well. The king offered him a high position. Joseph asked to be made controller of the granaries, so that he could guard the nation's harvest and thereby safeguard it during the anticipated drought. By this Joseph did not mean to seize an opportunity or personal gain; he merely wanted to rescue hungry nations for a period of seven years. It was a sheer self-sacrifice on his part.
Joseph's High Position - Qur'anic
Almighty Allah said: And the king said. "Bring him to me that I may attach him to my person." Then, when he spoke to him, he said: "Verily, this day, you are with us high in rank and fully trusted."
(Joseph) said: "Set me over the store-houses of the land; I will indeed guard them with full knowledge" (as a minister of finance in Egypt. in place of Al- Aziz who was dead at that time).
Thus did We give full authority to Joseph in the land, to take possession therein, as when or where he likes. We bestow of Our Mercy on whom We please, and We make not to be lost the reward of Al-Muhsineen (the good-doers). Surah 12: 54-57
