Allahu Akbar

Definition: Although most often translated as "god is great," Allahu Akbar is Arabic for "god is greater," or "god is greatest."

The phrase, known as takbir in Arabic, is expressive of a range of moods and occasions in the Islamic world, from displays of approval and happiness to entreaties or spiritual and at times propagandistic cheerleading during political rallies.

Allahu Akbar is also spoken during salat, the five-times daily prayer, and by muezzin as they chant the call to prayer from their minarets.
