Imam Mahdi's Analytical Genealogy from the Viewpoint of Shia and Sunni

Although the issue of Mahdaviyyat and the advent of Imam Mahdi (AS) at the end of the day are Shia and Sunni consensus, there are differences of opinion between the two in some of the themes of the Prophet. One of the controversies is the discussion of the birth of Imam Mahdi (aj). The consensus of the Shia and some of the Sunni people, based on the subsequent narrations, is that the Prophet is the descendant of the Prophet (pbuh) and the descendant of Fatima Zahra (sa) and of the descendants of Imam Hussein (AS). They also believe that he is the son of Imam Hasan Askari (AS). However, some Sunni people, especially those who do not have the opposite and even the hostility to followers of the Ahlul-Bayt (AS), sometimes doubt that they are from the descent of Abbas ibn Abdulmutallab, not from the Etruth and Ahlul Bayt (AS). Sometimes they say that he is from the generation of Imam Hassan Mojtaba (AS), not from the generation of Imam Hussein (AS). They also say that his father's name is Abdullah, not Imam Hasan Askari (AS). They have documented such doubts into some of the traditions that will be verified by the examination of their scriptures and documents, which are all mursal and narcissistic, and with special motivations by the perpetrators of history (especially in the age of the Abbasids) From the perspective of the Persian (Shia and many Sunni), they are untrustworthy and are considered news stories.
