Concept of The Messiah in the World’s different Religions:

In Christianity, the Messiah is Jesus, who is believed to be the Son of God and the savior of
humanity. In Judaism, the Messiah is a future leader who will usher in an era of peace and prosperity for the Jewish people. In Islam, the Messiah is known as the Mahdi and is believed to be a descendant of the Prophet Muhammad who will appear before the end of the world to restore justice and righteousness. In Hinduism, the concept of a messiah is not as prominent, but there are certain figures such as Kalki who are believed to bring about the end of the world and the start of a new era.

In Islam, the Messiah is known as the Mahdi and is believed to be a descendant of the Prophet Muhammad who will appear before the end of the world to restore justice and righteousness. The belief in the Mahdi is not universally held among Muslims and is particularly emphasized by Shia Muslims. According to Shia tradition, the Mahdi will be the final Imam, who will appear with Jesus to defeat the forces of evil, establish peace, and bring about the end of the world. Sunni Muslims also have a belief in the coming of a savior-like figure, known as the "Mahdi" but it is not as emphasized as the Shia belief. The concept of the Mahdi is not mentioned in the Quran, but it is based on Hadith and Islamic tradition.

In Judaism, the Messiah is a future leader who will usher in an era of peace and prosperity for the Jewish people. The belief in the coming of the Messiah is a fundamental aspect of Jewish theology and is rooted in the Hebrew Bible and Jewish tradition. According to Jewish tradition, the Messiah will be a descendant of King David, who will restore the kingdom of Israel, rebuild the Temple in Jerusalem, and bring about the ingathering of the Jewish people to the land of Israel. The Messiah will also be a political leader who will bring about the end of oppression and the establishment of a just society. Additionally, the Messiah will be a spiritual leader who will bring the knowledge of God to all nations and bring about the ultimate redemption of humanity. The concept of the Messiah is not limited to the Jewish religion but also present in Christianity and Islam.

In Hinduism, the concept of a messiah is not as prominent as in other religions. However, there are certain figures such as Kalki who are believed to bring about the end of the world and the start of a new era. According to Hindu tradition, Kalki will be the final incarnation of the god Vishnu, who will appear at the end of the current age of darkness and ignorance (known as Kali Yuga) to restore righteousness and destroy evil. He is often depicted riding a white horse and wielding a sword. Kalki will usher in a new age of peace, prosperity and enlightenment known as Satya Yuga.

 Additionally, in Hinduism, the ultimate goal is not salvation or redemption but rather the attainment of spiritual liberation (moksha) for the individual soul through the attainment of knowledge and union with the ultimate reality. The belief in messiah or a savior is not central in Hinduism but rather depends on the sect, tradition and personal beliefs.
