I hope this helps and, as always, peace to you!
Peace to you Shelby. It does help me understand how you view the world. However, you just happen to be wrong on this. Allah is not related to Hallelujah at ALL. It is related to elhohim. Arabic and Hebrew have ancient shared roots but are widely diverged. You are simply taking the english form of two totally different words and relating them. It would be like me saying collected and sold seashells for a living because Shelby and shell happen to share four letters.
Allah is derived from two words, "al" and "ilah", the Arabic cognate of the feminine semitic "eloah". It literally means "The God". It has nothing to do with Ishmael or Muhammed or Muslims. These words and names were around long before imaginary Ishmael ever was put to papyrus.
