(1) B, A, N, and M read: “Ibn al-Jārūd”; ʿA reads: “Ibn Abī al-Jārūd.” The correct reading is the one printed here. He was Abū al-Jārūd, Ziyād ibn Abī Ziyād al-Mundhir al-Hamadhānī al-Khurāsānī al-ʿAbdī. His honorific name was Abū al-Najm, and he was also sometimes called al-Nahdī and al-Thaqafī al-Kūfī. He died sometime between 150 and 160 AH and was the leader of the Jārūdiyya, a branch of the Zaydiyya. Al-Shahrastānī relates that Jaʿfar al-Sādiq named him Sarhūb. Al-Bāqir explained that Sarhūb was a blind demon dwelling in the sea. According to al-Nawbakhtī, Abū al-Jārūd was blind in both sight and heart. The Jārūdiyya claim that the Prophet—may Allah bless him and grant him peace—designated ʿAlī by description rather than by name, thereby making him the Imam after the Prophet. They further maintain that the people went astray and disbelieved by failing to follow him after the Messenger—may Allah bless him and grant him peace. According to them, the Imam after ʿAlī was al-Hasan, followed by al-Husayn. Thereafter, the Imamate was to be decided by consultation among the descendants of al-Hasan and al-Husayn. The Jārūdiyya also affirmed the doctrine of the Mahdī. Some of them held that the knowledge of the descendants of al-Hasan and al-Husayn was like the knowledge of the Prophet—may Allah bless him and grant him peace. On Abū al-Jārūd and the Jārūdiyya, see: al-Nawbakhtī, *Firaq al-Shīʿa* (al-Haydariyya ed., Najaf, 1379/1959), pp. 75–78; *Maqālāt al-Islāmiyyīn*, 1/66–67; *al-Milal wa-l-Nihal*, 1/140–141; *al-Farq bayn al-Firaq*, pp. 22–24; ʿAlī Sāmī al-Nashshār, *Nashʾat al-Fikr al-Falsafī*, 2/177–181. (2) B and A read: “those who claimed.” (3) The text enclosed in square brackets is absent from N and M. (4) “Learned” is absent from B. A reads: “and was a distinction,” which is a textual corruption. (5) B and A read: “then he is an imam.”
