The Islamic State’s videos regularly feature very short nasheeds not released as individual productions by Ajnad Media. One example was covered on this blog here regarding Boko Haram’s pledge of allegiance to the Islamic State to become West Africa Province. Below is another of these nasheeds, by no means wholly new but featured most recently in a Ninawa Province video regarding the renewal of allegiance from the tribes of the Ninawa plain. For the focus on Baghdad and Damascus, compare with e.g. the nasheed ‘Squadrons of my State’ from the ISIS era (pre-Caliphate declaration).
“This path and these banners,
So execute your order: it is Islam.
The light of guidance has returned on high, spreading.
Baghdad has risen, and al-Sham [Damascus] has awakened.”
