 The belief in the reappearance of the expected Mahdi, may Allah hasten his appearance, the universal reformer is not confined to the Shi'ite Muslims, other Islamic groups and even non-Islamic groups like the Jews and the Christians and some of the great world intellectual figures believe in the appearance of a great spiritual reformer, in Psalm 37 is written, trust in the Lord and do good, so you will dwell in the land and enjoy security, for the weak shall be cut off, but those who wait for the Lord shall possess the land, but the weak shall possess the land, delight themselves in abundant prosperity, the Lord knows the days of the flawless and their heritage will abide forever, for those blessed by the Lord shall possess the land, but those cursed by Him shall be cut off, the righteous shall possess the land and dwell upon it at peace forever. In the Holy Quran, a time is promised when the worshippers of truth, the world's people of righteousness, will take over the power and government of the world, and the glorious in of Islam will reign all over the earth, other aya's have been revealed which exegetically point to Hazrat Mahdi, peace be upon him, for we have written in the Psalms after the remembrance the earth shall be the inheritance of my righteous servants, Allah has promised those of you who believe and do righteous deeds that He will surely make you successors in the land, and even as He made those who were before them successors and that He will surely establish their religion for them and will give them in exchange after their fear, security, they serve me, not associating with me anything or in another place, but as He who has sent His messenger with the religion of truth that He may live above every religion, though we unbelievers be averse, yet we desire to be gracious to those that were based in the land and to make them leaders and to make them the inheritors. The above aya's clearly show that in the end, they will fall to the hands of Allah, worthy and righteous servants and that they will become the leaders of the people of the world, then Islam will be victorious over all religions, Allah may hasten His appearance.
