Harakat Ahrar al-Sham al-Islamiyya, commonly referred to as Ahrar al-Sham, is a coalition of multiple Islamist and Salafist units that coalesced into a single brigade and later a division in order to fight against the Syrian Government led by Bashar al-Assad during the Syrian Civil War. Ahrar al-Sham was led by Hassan Aboud until his death in 2014. In July 2013, Ahrar al-Sham had 10,000 to 20,000 fighters, which at the time made it the second most powerful unit fighting against al-Assad, after the Free Syrian Army. It was the principal organization operating under the umbrella of the Syrian Islamic Front and was a major component of the Islamic Front. With an estimated 20,000 fighters in 2015, Ahrar al-Sham became the largest rebel group in Syria after the Free Syrian Army became less powerful. Ahrar al-Sham and Jaysh al-Islam are the main rebel groups supported by Turkey. On 18 February 2018, Ahrar al-Sham merged with the Nour al-Din al-Zenki Movement to form the Syrian Liberation Front.
The Farouq Brigades, also spelt Farooq and Farook, was an armed rebel organisation formed by a number of Homs based members of the Free Syrian Army early in the Syrian Civil War.

By 2014, the group was largely defunct, with member factions joining other rebel groups. The brigades were named Farouq after Omar bin al-Khattab, a Sahaba (companion) of the Islamic prophet Muhammad and the second Caliph.

The inter-rebel conflict during the Syrian Civil War has continued throughout the Syrian Civil War as factions of the Syrian opposition and Free Syrian Army have fought each other, with shifting alliances among various Islamist factions such as Jabhat al Nusra, Ahrar al-Sham, Jaysh al-Islam and the Islamic Front.

Jund al-Aqsa, later known as Liwa al-Aqsa after 7 February 2017, was a Salafist jihadist organization that was active during the Syrian Civil War. Formerly known as Sarayat al-Quds, the group was founded by Abu Abdul 'Aziz al-Qatari as a subunit within the al-Nusra Front. The group later became independent, because al-Nusra was growing too rapidly for its resources and had suffered from fighting the Islamic State of Iraq and the Levant. On 20 September 2016 the U.S. Department of State designated Jund al-Aqsa as a terrorist organization. The group rejoined al-Nusra Front, by then renamed Jabhat Fateh al-Sham (JFS), in October 2016. However, on 23 January 2017, JFS declared that Jund Al-Aqsa was no longer part of Jabhat Fateh Al-Sham. In early February 2017, some of Jund al-Aqsa's units joined the newly formed Tahrir al-Sham, while the others refused and formed a new splinter group called Liwa al-Aqsa, and captured many towns in northern Hama and southern Idlib from other rebel groups. Following these attacks, Tahrir al-Sham launched a military operation against Liwa al-Aqsa, accusing them of being an ISIL affiliate. Following intense clashes with Tahrir al-Sham, up to 2,100 Liwa al-Aqsa militants left Idlib Province to join ISIL in Raqqa Province, by 22 February 2017.
The Nour al-Din al-Zenki Movement was a Sunni Islamist rebel group involved in the Syrian Civil War.

Between 2014 and 2015, it was part of the Syrian Revolutionary Command Council and recipient of U.S.-made BGM-71 TOW anti-tank missiles. The Movement made multiple attempts to merge with the larger Islamist rebel group Ahrar al-Sham but were refused by Ahrar al-Sham's leadership. The Zenki Movement also made attempts to merge with other Islamist factions, Jaysh al-Islam and the Sham Legion. However, all merging efforts with these groups failed, leading to the Zenki Movement joining the more hardline Hayat Tahrir al-Sham (HTS) in 2017. But after a few months the group left HTS and within a year went to war with HTS by joining the Turkish-backed Syrian Liberation Front alongside Ahrar al-Sham on 18 February 2018.
