Thanks Cal!
“Obama recited, “with a first-class [Arabic] accent,” the opening lines of this prayer:”
“Allah is Supreme! Allah is Supreme!
Allah is Supreme! Allah is Supreme!
I witness that there is no god but Allah
I witness that there is no god but Allah
I witness that Muhammad is his prophet... “
That is also called the Shahada.
The Shadada is the Muslim declaration of belief and acceptance of Muhammad as his prophet.
