God Is Greater
Many Muslims and their apologists claim "Allahu Akbar" is simply the Arabic translation of a common English phrase meaning "God is great!" However, this is untrue. "Allahu Akbar" does not mean "God is great" as claimed. It actually means "Allah is greater."
'Allah' is not simply the Arabic word for 'God,' but the name of Islam's chosen deity and 'Akbar' does not mean 'great', but 'greater'. Greater than what? The answer is, Allah is greater than whatever god you happen to believe in.
