Ayyub Faleh Hassan al-Rubaie (Arabic: أيوب فالح حسن الربيعي born 1978), known by his nom de guerre Abu Azrael (Arabic: أبو عزرائيل, literally "Father of Azrael"), also known as the "Angel of Death" (Arabic: ملاك الموت), is a commander of the Kataib al-Imam Ali, an Iraqi Shi'a militia group of the Popular Mobilization Forces that is fighting ISIL/ISIS (Islamic State of Iraq and the Levant) in Iraq. He has become a public icon of resisting ISIL in Iraq among Shia Iraqis with a large following on social media. His motto and catchphrase is "Ella Tahin" (Arabic: إلّا طحين), literally meaning "Until/into dust" interpreted to mean "Grind you to dust."
Abu Azrael is described in various sources as a Shi'ite who is a 40-year-old former university lecturer and a one-time Taekwondo champion, although other sources dispute that and suggest that this back-story may be fabricated. According to an Iranian source, he has a master's degree in physical education.
Reports from March 2015 claimed that Azrael is a father of five, and lives an "ordinary life" when not on the battlefield.
Following the viral video showing Abu Azrael striking the burnt corpse of a dead ISIS fighter with a sword, American political adviser Ali Khedery was quoted as saying "War crimes are never justifiable. Horrific video featuring a war crime by Iraq's Abu Azrael". Abu Azrael later said that the victim was a foreign fighter.
Beside this, on 31 May 2017, a video surfaced showing Abu Azrael lighting the beard of a dead ISIS fighter on fire, laughing and spitting at him while it burns. The video ends with one of his fellow soldiers stomping the face of the dead ISIS fighter, putting out the burning beard. 
Abu Azrael is currently fighting against ISIS although he has also fought against other militant groups. He has attracted attention in the Middle East, but by the spring of 2015, he had also made front-page appearances on international news websites in England, France and the United States.
He has received a medal of honor from the Representative of the Supreme Religious Authority Sayyid Ahmad al-Safi.
