(13) Ali bin Ahmad narrated from Obaydillah bin Musa from Ahmad bin Muhammad bin Khalid from Ali bin al-Hakam from Abban bin Uthman from al-Fudhayl bin Yasar that Abu Abdullah Ja’far bin Muhammad as-Sadiq had said:

“Whoever invites people to follow him and there is someone better than him among people, is a deviate and heretic and whoever pretends that he is an imam inspired by Allah, is an unbeliever.” After all, what about those, who have pretended to be imams whereas, in fact, they are not, who have denied one of the inspired imams and who have claimed that they, who have done so, are still faithful Muslims? Have they not been among those, whom Allah will never speak to, will never look on and will prepare the painful torment for on the Day of Resurrection? Have they not been among the unbelievers and the polytheists?
