The Islamic call to prayer is transliterated from written Arabic as Allah akbar
and is generally translated "God is great," though it can also be
translated "God is greater," "God is most great," or more loosely, as
our Turkish partners do it, "Allah the Almighty."
When spoken, an
additional syllable appears between the two words, which can be rendered
Allah-u akbar, but unless stressing pronunciation, NGS style prefers Allah akbar.
