the batariya
The Batariya were among the sects of the Zaydis. They were the companions of Kathir al- Nawa, al- Hasan b. Salim b. Abu Hafsa, al-Hakam b. 'Ayyina, Salama b. Kuhail, and al- Miqdam Thabit al Hadad. They (the Batariya) summoned (people) to the Imamate of 'Ali, peace be on him, then they mixed 'Ali's Imamate with that of Abu- Bakr and 'Umar, and proved the Imamate for them. They dispraised 'Uthman, Talha, al- Zubayr, and 'A'isha. It is said: "They were called the Batariya when they mentioned their beliefs before Zayd b. 'Ali, so he said to them: 'You have cut off our instruction when you have left Allah." And it is said: "They were called the Bataris because they were attributed to Kathir al- Nawa whose hand was amputated." 47
If this attribution was right, then they would be called al- 'Abtariya, not al- Batariya.
