Shaykhut Taifa says in Kitab Ghaibat :
The first one of them is the one known as Shari. A group of scholars narrated to us from Abu Muhammad Talakbari on the authority of Abu Ali Muhammad Ibne Himam, saying, Shari’s patronymic was Abu Muhammad. Harun said: I think his name was Hasan and he was from the companions of Abul Hasan Ali Ibne Muhammad and then after him from the companions of Hasan Ibne Ali.He is the first one who claimed a position that Allah did not assign to him and he was not qualified for it.
He blasphemed Allah and his Hujjas, peace be unto them, and attributed to them what is not worthy of them andthey are disdainful thereof. The Shia cursed him and turned away from him with dislike. Harun says, Then words of disbelief and sacrilege were expressed by him. All such claimants, first, attribute lies to the Imam and claim that they are his representatives, calling the weakling to believe in them through such pervert claims. Then they graduate up to the claims of self deification, like the words of Hallaj as manifested by Abu Ja’far Shalmaghani and his likes. On all of them be the constant curses of Allah. One of them is Muhammad Ibne Nasir Numairi.
