Joseph embraced them, and together they wept with joy. It was not possible for Joseph to leave his responsible office without proper replacement, so he advised his brothers: "Go with this shirt of mine, and cast it over the face of my father, he will become clear-sighted, and bring to me all your family. " Surah 12: 93
And so the caravan headed back for Palestine. We leave the scene in Egypt and return to Palestine and the house of Jacob. The old man is sitting in his room; tears have been flowing down his cheeks. He stands up all of a sudden, dresses and goes out to his sons' wives. Then he lifts up his face to Heaven and sniffs the air.
The wife of the eldest son remarked: "Jacob has come out of his room today." The women inquired about what was amiss. There was a hint of a smile on his face. The others asked him: "How do you feel today?"
He answered: "I can smell Joseph in the air."
The wives left him alone, saying to one another that there was no hope for the old man. "He will die of weeping over Joseph."
"Did he talk about Joseph's shirt?"
"I do not know. He said he could smell him; perhaps he has gone mad."
That day the old man wanted a cup of milk to break his fast, for he had been fasting. At night he changed his clothes. The caravan was traveling in the desert with Joseph's shirt hidden among the grain. It neared the old man's estate. He gesticulated in his room, and then he prayed a long time, lifting his hands to heaven and sniffing the air. He was weeping as the shirt was nearing him.
And when the caravan departed, their father said: "I do indeed feel the smell of Joseph, if only you think me not a dotard (a person who has weakness of mind because of old age)."
They said: "By Allah! Certainly, you are in your old error."
Then, when the bearer of the glad tidings arrived, he cast it (the shirt) over his face, and he became clear-sighted. He said: "Did I not say to you, 'I know from Allah that which you know not.
They said. "0 our father! Ask Forgiveness (from Allah) for our sins, indeed we have been sinners." Surah 12: 94-97
