“I said to Imam Abu Abdullah as-Sadiq (as): “Someone has sent you his regards and requested you to intercede for him (on the Day of Resurrection).” Imam as-Sadiq (as) said: “Is he from our followers?” I said: “Yes, he is.” He said: “His matter is more important than that.” I said: “He has believed in Ali but he does not know any of the guardians after him.” He said: “He is astray.” I said: “He has believed in the imams but he has denied the last one of them.” He said: “He is like that who believes in Jesus Christ and denies Muhammad or believes in Muhammad and denies Jesus Christ. We pray Allah to protect us from denying any of His authorities.” Let one, who reads this tradition, be careful not to deny any one of the imams lest he will perish as if he has denied Muhammad or Jesus Christ (peace be upon them).
