Harakat Sham al-Islam (Arabic: حركة شام الإسلام, meaning "Islamic Movement of the Levant") is a jihadist group composed of primarily Moroccans that has been active during the Syrian Civil War.^[18] The group announced on 25 July 2014 that it became part of the Jabhat Ansar al-Din.^[3] It was designated as a terrorist organization by the US State Department on 24 September 2014,^[22] by United Nations on 29 February 2016.^[23] and by Bahrain and Morocco.^[24][25]

The group was founded in August 2013 by Moroccans Brahim Benchekroun, Mohamed Mazouz, and Mohammed Souleimani Laalami, who had been released from the Guantanamo Bay detention camp.^[26][27] Harakat Sham al-Islam first came to notice because of the role it played in the 2013 Latakia offensive.^[28] The following year the group was one of the three primary factions, alongside Al-Nusra Front and Ansar al-Sham, that took part in the 2014 Latakia offensive.^[29] Harakat Sham al-Islam also has a presence in Aleppo, being involved in battles for Kindi Hospital and the Aleppo Central Prison.^[28]

The group's leader, Shakran, was killed in a battle with Syrian government forces in April 2014,^[30] along with the group's military commander, Abu Safiya Al-Masri.^[31] On 12 December 2016 they fully dissolved into Jabhat Ansar al-Din.^[2]

Harakat Fajr ash-Sham al-Islamiya (Arabic: حركة فجر الشام, Islamic Dawn Movement of the Levant) is a jihadist group that has been active during the Syrian Civil War.^[32] The group announced on 25 July 2014 that it became part of the Jabhat Ansar al-Din.^[3] On 12 December 2016, the group fully dissolved into Jabhat Ansar al-Din.^[2]

On 2 August 2018, Ansar al-Haqq and Abna Sharia joined.^[6]

On 20 August 2018, Fursan al-Iman joined the group.

The group has stated they desire to maintain a policy of neutrality and independence between various groups in fighting against the Syrian government as well as stating a desire to cooperate with these groups as well,^[8] prior the formation of the group the member groups did cooperate with ISIL in early 2014 in besieging the Kweiris airbase.^[34]

In an interview in 2015 a representative from the group was asked about their views regarding both al-Nusra and ISIL to which the representative said regarding al-Nusra "The problem is with them, not with us: we are prepared to work with all upright factions whose goals are like ours. It is not hidden from anyone that the goals of the majority of factions are like our goals." He added when asked if al-Nusra has made mistakes on the ground "In my personal opinion indeed we all make mistakes…and perhaps in Jabhat al-Nusra’s point of view it is not necessary to establish a Caliphate while the gangs of Assad exist in Syria." When asked about the group's stance on ISIL he said "We have no relation with IS (Islamic State). We don’t fight them and they don’t fight us. But anyone who says that Jabhat Ansar al-Din is affiliated with IS is lying."^[8]

Abu Salah al-Uzbeki and 50 other fighters defected from Hay'at Tahrir al-Sham (HTS) and joined the group in 2020.^[35]
