7. Muhammad ibn Yahya has narrated from Ahmad ibn Muhammad from Muhammad ibn ’Isma‘il from Mansur ibn Yunus from Muhammad ibn Muslim who has said the following.

“I said to abu ‘Abdallah , “A man said to me, “You must know the last of the Imams and it does not matter if you would not know the first of the Imams.” The narrator has said that the Imam said, “May Allah condemn this. I am angry with him and I do not know him. How can the last Imam be recognized except through the first Imam?”
