Abu Basir al-Asadi was in the company of Muhammad al-Baqir for a long time and after that he became one of the companions of Jafar al-Sadiq.
Abu Basir's name is included in the number of six companions of al-Baqir and al-Sadiq[1] that hadiths narrated by any one of them is considered authentic by many Shi'a scholars.
[2][1] A large number of religious and jurisprudential traditions in Imamiyyah hadith books, which were narrated from al-Sadiq through Abu Basir, show the extent of their association.Shaykh Tusi listed him among the companions of Musa al-Kadhim too.
The Imam offers him a choice: he can remain as he now is (i.e., sighted), though if he does, then on the Day of Resurrection he will have to face the final judgement; or he can return to the state of blindness and be assured of Paradise (laka l-janna khāliṣan/ khāliṣatan).
"[4] Abu Basir al-Asadi was considered one of the poles of the intellectual leadership of the Imami community of Kufa, there are several traditions that show that Abu Basir (apparently Asadi) was present in the scenes of intellectual struggle with opposing groups such as Mokhtariyah and Zaidiyyah.
In various sources, information has been narrated through Ali bin Abi Hamza, which states that Abu Basir (Asadi) shortly after the death of al-Sadiq, while Abdullah al-Aftah was still alive, went to Hijaz to perform Hajj and met al-Kazim and has declared his loyalty to the Imam.
Ali ibn Abi Hamzah and his son Hasan, who also followed the Waqifi religion, have used the traditions of Abu Basir in their works much more than other companions of the imams.
In addition to what was mentioned, there was a writing by Abu Basir about the conditions of the first imams according to the narration of Muhammad ibn Sinan cited in some old works of Imamiyya and others.
