The Tawussite Shia (attributed to Ajlan ibn Tawus) were a Shia group who were a section of the supporters of Imam Ja'far al-Sadiq who denied admitting that he died. They believed that he was the Awaited Mahdi and that he was alive and did not die.[1]
After the death of Imam Muhammad al-Baqir, the defeat of Muhammad ibn Abdallah An-Nafs Az-Zakiyya, the triumph of the Abbasids, and the popularity of Imam Ja'far al-Sadiq, reports became widespread on his Mahdism.[2] Al-Nubakhti reports that: “Some Shiites (i.e. Tawussites) have reported (falsely) from Imam Sadiq that he said: ‘If you see my head rolling to you from the mountain, you should not believe that, for I am your Sahib (Mahdi)’” and: “If anyone informs you that he nursed me, washed my body (after death) and shrouded me, do not believe him, I am your companion (Sahib) and the companion of the sword.”[3]
Among the Tawussites was Aban ibn Uthman al-Ahmar, who was considered by Shia scholar al-Kashi to have been one of the men of Ijma (consensus), i.e. one of the supposed closest people to Imam Sadiq.[4]
