Occultation of Prophet Yusuf (a.s.)

Narrated to us my father; and Muhammad bin Hasan – may Allah be pleased with
them – they said: Narrated to us Abdullah bin Ja’far al-Himyari from Ahmad bin Hilal Isa
from Abdur Rahman bin Abi Najran from Fadala bin Ayyub from Sadeer who said: I heard
Aba Abdullah (a.s.) say:

“The Qaim is also having a similarity to Prophet Yusuf (a.s.).” The narrator
says: I said: Perhaps you want to tell us about him or his occultation. He told me:

“In this Ummah, the opponents who resemble swine, don’t oppose that Yusuf’s
brothers were among the children of prophets but they sold away Yusuf while all
of them were his brothers and he was also a brother to them, yet when they met
they could not recognize him till Yusuf introduced himself and said: “I am Yusuf
and this is my brother.” Thus how can this Ummah deny if the Almighty Allah
wants to keep His Proof concealed from them in a period of time? And one day
Yusuf became the king of Egypt and the distance between him and his father was
only of 18 days’ travel. When Allah, the Blessed and the High wanted that his
status and value be recognized, by Allah, the people of his house covered this
distance in nine days after getting the glad news. Thus how can this Ummah deny
that Allah, the Mighty and Sublime can do with His Proof the same as what He
had done with Yusuf? His Proof should walk among them, pass by them in the
markets and sit among them and they could not recognize him. Until Allah, the
Mighty and Sublime permits the Divine Proof to introduce himself as He had
permitted Yusuf (a.s.) to do so when he said:
 
قَالُواْ أَإِنَّكَ لَأَنتَ يُوسُ فُ قَالَ O هَلْ عَلِمْتُم مَّا فَعَلْتُم بِيُوسُفَ وَأَخِيهِ إِذْ أَنتُمْ جَاهِلُونَ
أَنَاْ يُوسُفُ وَهَذَا أَخِي

Do you know how you treated Yusuf and his brother when you were
ignorant? They said: Are you indeed Yusuf? He said: I am Yusuf and this is
my brother.
(Surah Yusuf 12:89-90)
