Al-Barradi mentioned that he saw and read all the above-mentioned documents and works except the Sirah of Muhammad b. Mahbub.37 It is reported that a complete copy of this Sirah, consisting of seventy parts, was available in Jabal Nafusah towards the end of the fourth century H., and only part six of the book was available in Jerba Island during that period.38 However, most of these works and documents are still extant except the works of Abu Sufyan and his son Muhammad b. Mahbub, K. Salim b. al-Hatiyah al-Hilali, the letter of Jabir b. Zaid to the Shi'ite, and the letter of Abu Bilal Mirdas. Al-Barradi preserved useful information from some of those missing works in his al-Jawahir,39 while al-Darjini in his Tabaqat preserved useful information about early Ibadhi authorities from K. Abu Sufyan Mahbub.40

There are earlier Ibadhi documents that deal with the subject still in existence, which can be consulted:

1. The Sirah of Salim b. Dhakwan, and Ibadhi scholar and contemporary of Jabir b. Zaid.41

2. The Sirah of Shabib b. 'Atiyah al-'Umani.42

3. The Sirah of Abu Qahtan Khalid b. Qahtan al-Hijari.43
