In the holy religion of Islam, the issue of the promised Savior and the Savior is clearly raised. The Quran, the holy book of Muslims, refers to the rule of the righteous on earth and the dominance of the true religion in numerous verses. Among them is verse 105 of Surah Al-Anbiya. In this verse, God states that My righteous servants will inherit and take possession of the earth. He also states that this is a truth that has been mentioned in the books of the past prophets. In verse 55 of Surah An-Nur, God promises people who believe and do righteous deeds that He will leave them the caliphate and government on earth and establish and establish their religion. At such a time, complete peace and security will be established in the world and people will worship and serve God.
God, in three places in the Quran (At-Tawbah: 33 and 34; Al-Fath: 28; Al-Saff: 8), states that the religion of Islam will prevail over all religions; although the disbelievers and polytheists do not want it and He introduces Himself as a witness to such an event. Of course, considering the narrations that have been issued in the interpretation and explanation of the divine verses from the infallible leaders, it can be seen that more than 250 verses of the Quran refer to Imam Mahdi (a.s.) and the rule of justice and religion. In addition to the Holy Quran, numerous narrations about him have been mentioned in important Shiite and Sunni books of narration, and numerous books have also been written specifically for that Imam; For example, we can mention Kamal al-Din and Tamam al-Naamah, by Sheikh Saduq, Al-Ghaybah, by Nomani and Kitab al-Ghaybah by Sheikh Tusi from past scholars, and Mantab al-Athar, by Lotfollah Safi Golpaygani from contemporary Shiite scholars, or Al-Fitn, by Ibn Hammad and Al-Arbaeen, by Abu Naeem Isfahani from Sunnis.
The Holy Prophet (PBUH) said: “Mahdi is from my lineage, from the descendants of Fatima (PBUH).”
It is appropriate to mention that according to Shia belief, Imam Mahdi (AJ) is the son of Imam Hassan Askari (AS), who was born in 255 AH and is now behind the veil of occultation and will be alive until God permits his reappearance and resurrection; however, according to Sunnis, he has not been born; rather, he will be born at the end of time, about forty years before his reappearance.
