Iraq (2004) Al-Qaeda (2004–2017) Syria Lebanon Maysar Ali Musa Abdullah al-Juburi (Arabic: ميسر علي موسى عبد الله الجبوري; 1 June 1976 – 4 April 2024), also known as Abu Maria al-Qahtani (Arabic: أبو ماريا القحطاني), was an Iraqi Islamic militant who fought in the Iraqi insurgency and then in the Syrian Civil War.

Maysar Ali Musa Abdullah al-Juburi was born on 1 June 1976 in Al-Shura in the Mosul District of Nineveh Governorate, Iraq.

While in Al-Qaeda in Iraq, he served as the head of the religious police of the organization overseeing the implementation of Sharia in areas under its control.

[3][5] While advocating for a separation from not just ISI[6] but from Al-Qaeda as a whole, he expressed dissatisfaction with others in the leadership of the Al-Nusra Front including Abu Mohammad al-Julani.

[7] Al-Qahtani was involved in infighting between factions[2] as well as internal disputes in Al-Nusra itself, which caused him to later be dismissed from his position as general Sharia official in 2014.
