Ahmed al-Hasan

Ahmed al-Hasan (Arabic: أحمد الحسن, romanized: ʾAḥmad al-Ḥasan) is an Iraqi Shia Muslim religious leader. He has been called the most prominent of figures claiming to be the pre-messianic al-Yamani, in the upheaval following the US invasion of Iraq in 2003. In Twelver Shi'ism Islam, the majority religion of Iraq, al-Yamani is "the deputy of the Mahdi, the Twelfth Imam, and a precursor to his Reappearance" and to End Times.

Ahmed al-Hasan, who was born in Iraq, started his call in 1999 and began a public "religious call" in 2002. He was last seen, photographed, and interviewed in 2007, and is presumed to have gone into hiding following the Battle of Najaf sometime in 2008. An office in Najaf claims to exclusively speak for him through various social media platforms including Facebook and Telegram, which his followers believe to be managed by Ahmed al-Hasan himself.
