1 - Narrated to us my father and Muhammad bin Hasan - May Allah be pleased with them - they said: Narrated to us Saad bin Abdullah from Hasan bin Isa bin Muhammad bin Ali bin Ja’far from his father from his grandfather Muhammad bin Ali from Ali bin Ja’far from his brother, Musa bin Ja’far that he said:

“When the fifth descendant of the seventh Imam goes into occultation, for the sake of Allah protect your religion. None of you must let go of your religion. O son, occultation is necessary for the master of this affair. So much so that even those who say that it is a test from Allah, they would also turn away from him. 

And if in the knowledge of your forefathers there had been some other religion more correct and better than this, they would have followed that only.” I asked: “Master, tell us who is the fifth descendant of the seventh Imam?” He replied: “Son, your intellects are small, he cannot be accommodated in it. Your understanding is so restricted that you cannot bear it, but if you live till that time you will indeed find him.”
