A popular jihadi nasheed also used by more mainstream Syrian rebels. Preliminary translation:
They said it was a promise: We are the league of the lion.
And our march left them in defeat, withdrawing forever.
Then they made their call. It had already been finished. Indeed it had been ordained.
For our response rendered them not only stunned but also defeated. [chorus]
Indeed we are the soldiers who burn disgrace with fire,
Your fraudulence has truly vanished in the winds of victory.
We will demolish your throne, we will destroy your dominion.
So depart forever. Indeed we see an abode for malice.
League of evil, depart forever. Hear the resolve from me.
Head to your abode forever, we are the knights of the day.
Depart without returning from endurance of the veil.
Drink a cup of humiliation, and take all the lowly ones.
