Ten Little Muslims is a song sung in an Oslo kindergarten to celebrate Eid.

One and two and three little Muslims,
Four, five and six little Muslims,
Seven and eight and nine little Muslims,
Ten little Muslims.

But hush, there was something whispering
Hush, there was something whispering
See, it was the deceiving Shaytan
Come, let us frighten him away

All children cry: Allahu Akbar!
All children cry: Allahu Akbar!
All children cry: Allahu Akbar!

See, there he's sneaking off.

And there was one and two and three little Muslims,
Four, five and six little Muslims,
Seven and eight and nine little Muslims,
Ten little Muslims.

The story behind this song, here.

Who is the Muslim Satan the kids are singing about?

Here is a partial answer:

"... hard-liners in Iran and elsewhere in the Muslim world have called the United States "the Great Satan" and Israel "the Lesser Satan."

Here is a more comprehensive attempt:

"The Islamic Satan is different and so is the Jewish one. In Christianity Satan is the Devil. But in Islam Satan can be the Devil (Iblis) or some evil person or a synonym of general evil. In Islam Iblis (Devil) is sometimes used as personification of evil but certainly not always. Islamic Satan is often a synonym of evil. Even today some Muslims call USA the big Satan, would you accuse them for thinking USA is the horned winged “monster”?"
