(Wikipedia)"The form Allāhu is the nominative of Allah "[the one] God" The form akbar is the elative of the adjective kabīr "great". In Semitic languages, an elative may indicate a superlative (best), or a comparative (better). The term takbīr (تَكْبِير) itself is the stem II verbal noun (tafʿīlun) of the triliteral root k-b-r "great".[1]
The word akbar as used in the takbir indicates the superlative, usually translated as "greatest". In Arabic usage, akbar may also be used as a comparative, in which sense it may be approximately translated as "greater", or "bigger" in some dialects (dictionaries carry both senses of akbar).
[edit] Usage This phrase is recited by Muslims in numerous different situations. For example, when they are happy or wish to express approval, when they want to praise a speaker, during battles, and even times of extreme stress or euphoria.
The phrase is said during each stage of both obligatory prayers, which are supposed to be performed five times a day, and supererogatory prayers, which are performed at will. The Muslim call to prayer, or adhan, and to commence the prayer, or iqama, also contains the phrase, which is heard in cities all over the Muslim world. Utterances in the Prayer.
Note that takbīr (تَكْبِير) is only the name of the expression, while the phrase itself is "Allahu Akbar". In the Islamic world, instead of applause, often someone will shout "takbir" and the crowd will respond "Allahu Akbar" in chorus.
During the Iranian revolution of 1979, the call was shouted from rooftops during the evenings as a form of protest. This practice returned in the aftermath of the 2009 Iranian presidential election.[2][3] The phrase has also been used after the election to show the protest of the people against the election results. Many people shouted this phrase from 22:00-23:00 for 9 days after the 2009 Iranian election to show their protest to the result."
If you view any horrific Islamist videos taken from a distance showing one of their successful IEDs against our guys in the field, the minute the frikkin things explode, they yell "Allahu Ahkbar". Also, in those execution videos of hostages popular a while back, at the time of severing those non-Muslims heads, Al-Zarkawi and his henchmen invariably yelled "Allahu Ahkbar".
Now. The question is. How is the Government Controlled MSM in the USA walk out of this one?
Simple. They don't mention it.
I just looked at the ABCNews story linked from Drudge. Not one mention of his being a Muslim on Page 1 of the story, which is as far as most people will read. I didn't read further, out of disgust.
