According to Islamic narrations, during the emergence of Imam Mahdi, he will confront various groups and sects as non-believers in him; however, he will adopt different methods against each group of his opponents because all of these disbelievers would not be the same. Of course, a majority of the disbelievers are the ordinary people who do not know the Imam and the magnificent rank of the Imamate so, at the beginning of his advent, the Imam will introduce himself to them and will try to convince them and guide them to the right path. But a few of them are such strict enemies that they will stand against the Imam in a way that they would be considered as the serious obstacles in the path of his divine mission; like tyrant rulers, the heads of false and deviant sects, and hypocrites, etc.
Besides, it should be noted that some sects or groups of people would not accept the Imam as a divine leader, but they also would not stand against the Imam and would not be rendered as an impediment on the way of his mission. As it is clear, the Imam will not move against them.
In this situation and on the threshold of establishing his government, it would necessary for the Imam to fight with those obstacles to uproot them. However, the method and diplomacy of Imam Mahdi in this regard generally is only the continuation of the conduct of his ancestor, Prophet Muhammad. In better words, though Imam Mahdi is the full embodiment of Divine mercy, his mode of conduct with the enemies and disbelievers depends on their reaction against him. In other words, Imam Mahdi, as the last savior for mankind, will not remain silent on any kind of tyranny at all.
Undoubtedly, bloodthirsty oppressors rule the world before and while the advent of the Mahdi. Now, in such a case, how could be possible for the Imam, who has risen against all this perversion and tyranny to remain silent? Clearly the opposition groups who have usurped the rights of people and whose positions have been endangered and whose hands are stained with the blood of human beings are standing up to the reformist Imam’s movement. Therefore, Imam Mahdi as the universal reformer who rises and has a mission to form ‘the one-world government’ must have a plan to remove the obstacles. Therefore, he will have to fight against the strict enemies of Islam to implement the divine justice hardly because in front of him, are the enemies armed to the teeth, with having access to the world’s vast economic potential and have benefited from the advanced technology and by enjoying powerful armies who will raise the flag of opposition.
