3. Muhammad ibn Yahya has narrated from Ahmad ibn Muhammad from al-Hassan ibn Mahbub from Hisham ibn Salim from Zurara who has said the following.

“I said to abu Ja’far , ‘Is knowing the Imam from among you obligatory on all creatures?’” The Imam said, “Allah, the Most Holy, the Most High, sent Muhammad to all people as His Messenger and as His authority over all creatures on earth. Those who have faith in Allah and that Muhammad is His Messenger and have followed him and have acknowledged his message on such people it is obligatory to the Imam from us. Those who do not have faith in Allah and in His messenger and who do not follow him and do not acknowledge him and do not acknowledge the rights of Allah and His messenger then knowing the Imam would be obligatory on them? They do not have faith in Allah and in His messenger, do not follow him and do not acknowledge their rights.” I then asked, “What would you say about those who have faith in Allah and His messenger who acknowledge His messenger in all the matters that have come from Allah, is it obligatory for them to know the Imam from you?” The Imam said, “Yes, it is obligatory. Do they not know so and so?” I said, “yes, they do.” The Imam then said, “Do you think Allah is the one who has placed such knowledge in their hearts? No, I swear to Allah that no one other than Satan has placed such knowledge in their hearts. I swear to Allah that no one other than Allah, the Most Holy, the Most High, has inspired our rights in hearts of the believers.”
