H 314 - Abu Nasr Hibtullah bin Muhammad bin Ahmad Katib Ibn binte Abu Ja’far Amari has narrated that: Abu Amr was from the Asadi tribe, but was called after his grandfather, Ja’far bin Amari. A group of our scholars have said that Imam Hasan Askari said: In one person two names, Uthman and Abu Ja’far cannot come together and Imam ordered his agnomen to be discarded; on the basis of this he began to be called as Amari and some have called him Askari as well, due to the fact that people from Askar province were also present in Samarrah. Some called him as Samman (oil dealer) as he traded in that commodity and through this concealed his deputyship.”
