A messiah is a special person who is believed to have been chosen by God to save people from harm and help bring peace and goodness to the world. In Islam, the messiah is called the Mahdi.
Muslims believe that the Mahdi will come at the end of the world and will help bring about justice and peace. It is said that he will be a descendant of the Prophet Muhammad and that he will lead people to true Islam.
The Mahdi is believed to have certain special powers, such as the ability to communicate with animals and the power to heal the sick.
Some Muslims believe that the Mahdi has already come and will reveal himself at a time when the world is in turmoil, while others believe that he has not yet arrived.
Overall, the belief in the Mahdi serves as a reminder to Muslims of the importance of working towards a just and peaceful society, and being prepared to welcome the Mahdi if he does come.
