Furthermore, a minority among the Sunnites do not accept that the Restorer will be called Mahdi and, indeed, entertain doubts as to his existence.
The Encyclopaedia of Islam asserts that: “Lingering doubts concerning the Mahdi may partly account for the absence of any traditions about him in the Sahihs of al-Bukhari (810/870 AH) and Muslim (817/875 [1] Ibid, p.1231 [2] “al- Mahdi ” SEI, p.311 [3] Sachedina, Islamic Messianism, P.14 AH).” [1] “There is no mention of the Mahdi in either of the two Sahih ’s of Muslim or Bukhari”. [2] There are also controversial discussions about whether the idea of Messianism rightly belongs to Islam or not.
Some claim that the idea of Messianism is not Islamic. The New Encyclopaedia Britannica says that “Islam is not a Messianic religion and has no room for a Saviour-Messiah.” [3] Riffat Hasan supports this thesis and states that: “Messianism appears to be incompatible with the teachings of the Qur’an, nonetheless in the Muslim world it is a widespread phenomenon, playing a pivotal role in the lives of many present-day Muslims from all segments of society.” [4] Also: “Normative Islam as embodied in the Qur’an does not support the idea of Messianism in any of its forms, while Messianism is an essential part of religious belief and practice for almost all Shi’a Muslims.
Shi’a Messianism does not fit theologically or logically into the framework of normative Islam.” [5] Riffat Hasan also relies on Fazlur Rahman’s comments showing that Messianism was not a part of original Islam.
He stated: “As for Messianism, it was originally adopted in Islam either by Shi’ism or Sufism, but in any case it came to Sunni Islam through the Sufis or rather through the precursors of the Sufis [1]“al- Mahdi “, EI², p.1234 [2] “al- Mahdi ” SEI, p.311 [3] “Messiah and Messianic Movements”p.1020 [4] R. Hasan: “Messianism and Islam”, p.262 [5] Ibid, p.267.
Indeed, early Sunni sources record several traditions from the Prophet about the appearance and attributes of the Mahdi .
