Islamic theology says that a messianic figure, known as Imam al-Mahdi among Shiites and Muhammad al-Mahdi among Sunnis, will emerge at the end of times to redeem Islam and rid the world of evil. Naming the figure is condemned by both sects, as it falls into the category of al-Ghaib (the concealed), which is information known only by God.
Sadr tweeted early Friday morning that he would not continue to lead the movement while the People of the Cause are part of it. “To be a reformer for Iraq… yet I cannot fix the Sadrist Movement, that would be a sin,” he said. All activities of the Sadrist Movement will be frozen for at least a year, excluding Friday prayers and an institute that promotes the teachings of Sadr's father, Muhamed Sadiq al-Sadr.
A few minutes later, he tweeted again, announcing that his Twitter account will be deactivated “until further notice.”
Sadr commands a large popular following and his movement has religious and charitable institutions. He was also involved in politics until he announced his “definitive retirement” last August after violent altercations broke out between his supporters and those of pro-Iran parties inside Baghdad's fortified Green Zone.

Not easy to live with Islam...
The Mahdi (Arabic: ٱلْمَهْدِيّ, romanized: al-Mahdī, lit. ‘the Guided’) is a messianic figure in Islamic eschatology who is believed to appear at the end of times to rid the world of evil and injustice. He is said to be a descendant of Muhammad who will appear shortly before the prophet ʿĪsā (Jesus) and lead Muslims to rule the world.

Al-Masih ad-Dajjal (Arabic: ٱلْمَسِيحُ ٱلدَّجَّالُ, romanized: al-Masīḥ ad-Dajjāl, lit. ‘Deceitful Messiah’), otherwise referred to simply as the Dajjal, is an evil figure in Islamic eschatology similar to the Antichrist in Christianity, who will pretend to be the promised Messiah and later claim to be God, appearing before the Day of Judgment
