The Idea of Global Government has attracted the attention of many scholars; what requests attention in the field consists in studying the subject based on Quran and traditions comparatively in the view of fariqain commentators. Quran and traditions have viewed the pious and the poor rule and conquest of Islam over other religions. Fariqain scholars, being in common on the idea of global government and on main statement of the proof, are in a partial disagreement. The paper has studied the subject on the basis of the verses of making prevail and making conquer comparatively. As is understood by such verses and commentary traditions, in addition to the necessity of global government, it has become clear that the government will be founded by Imam Mahdi and arguments and proofs will be given on the day of conquest of Islam over all religions.
