This is Philadelphia.
The children are at an event for the Muslim American Society Islamic Center in Philadelphia (MAS Philly).
From MEMRI:
Child Narrator: Those who accept humiliation – what is the point in their existence? Those who reject oppression are the ones who assert their existence, and they eliminate the injustice from the land of the Arabs.Here are some more excerpts:
Children Singing: Rebels! Rebels! Rebels! Glorious steeds call us and lead us onto paths leading to the Al-Aqsa Mosque. The blood of martyrs protects us. Paradise needs real men!
The land of the Prophet Muhammad's Night Journey is calling us. Our Palestine must return to us. Oh Saladdin, your men are among us – shame will be washed away!
[You need] force and the Quran, oh free people! We must persevere no matter what happens, and with the help of the Omnipotent Lord, day will follow night.
Take us, oh ships, until we liberate our lands – until we reach our shores and crush the treacherous ones!
Blow, oh winds of Paradise – flow, oh rivers of martyrs! My Islam is calling, who is going to heeds its call? Rise, oh righteous ones!
Girl 1: Our martyrs sacrificed their lives without hesitation. They attained Paradise, and the scent of musk emanates from their bodies. They compete with one another to reach Paradise. Will Jerusalem be their capital city, or will it be a hotbed for cowards?
Girl 2: We will defend the land of divine guidance with our bodies, and we will sacrifice our souls without hesitation. We will chop off their heads, and we will liberate the sorrowful and exalted Al-Aqsa Mosque. We will lead the army of Allah fulfilling His promise, and we will subject them to eternal torture.
