The Ajnad al-Sham Islamic Union (Arabic: الاتحاد الإسلامي لأجناد الشام, romanized: al-ittihad al-islami li-ajnad al-sham, "Islamic Union of the Soldiers of the Levant") was an alliance of Sunni Islamist groups affiliated with the Muslim Brotherhood[9] that was active in the Rif Dimashq Governorate during the Syrian Civil War.

[5] In early November 2013, a large number of Sunni Islamist rebel groups in the wider Damascus region announced the formation of the “Greater Damascus Operations Room”, excluding Jaysh al-Islam and the most radical jihadis al-Nusra Front and the Islamic State of Iraq and the Levant.

[9] As a result, Ajnad al-Sham Islamic Union fighters based in eastern Ghouta, including the entire Habib al-Mustafa Brigades and Battalions, announced their "full incorporation" into the al-Rahman Legion, though reiterating that its fighters based in the western Damascus suburbs of Darayya and Muadamiyat as well as in southern Damascus would still operate under the Ajnad al-Sham Islamic Union banner and were not a part of this merger.

[9] On 26 February 2016, Syrian Army Special Forces killed the second leader of the Ajnad al-Sham Islamic Union, Faysal al-Shami ("Abu Malek"), after intense clashes in the Darayya Association Quarter.

[1] On 19 March 2017, Ajnad al-Sham Islamic Union fighters who left Darayya and Muadamiyat between August and October 2016 as part of the evacuation deal to Idlib joined the Sham Legion,[11] reducing the presence of the Ajnad al-Sham Islamic Union to two pockets in the Damascus and Rif Damascus areas.
