Obstacles that the Islamic Ummah poses to Imam Mahdi (AS) after the advent

Imam Mahdi (AS) will appear as the ultimate divine authority on earth with the goal of reforming humanity and spreading justice and morality in the world. Naturally, He will face obstacles to achieve his goals, as it has been mentioned in narratives (Hadith), such a victory cannot be achieved except with much difficulty. Some of these obstacles come from within the Islamic Ummah and they are related to the Muslims. This is especially important because, these obstacles lie within the religion against the real leader of that religion. This impediment to the impediments that non-Muslims face in front of Imam is more influential. Using the Ravayats , inter-religious barriers can be divided into four basic categories . The first category is Misbehavior of some Sadat. The second is the religious barriers that are divided into two groups: Shia and Sunni. Third, the obstacles encountered by some tribes from different Geographical areas for the Imam (aj). The fourth obstacle is the flow of hypocrisy, which, according to some Ravayats, will stand up against him.
