Here is a collection of Anāshīd I gathered in the last few days.
Anasheed / Anāshīd (Arabic: singular نشيد nashīd, plural أناشيد Anāshīd, meaning: “chants”), is Islamic vocal music that is either sung a cappella or accompanied by percussion instruments such as the daff. Anāshīd usually reference to Islamic beliefs, history, and religion, as well as current events.
And the war in Syria is most definitely one of the events recent Anāshīd cope with. A small overview of recent Anāshīd mostly published by Jabhat an-Nusra accompanying videos of recent military successes.
