Hello runninglikezebras,
Well, you have a very argumentative nature. Well, stubbornness is good, if what you say is right.
You want more sources from my part which are not Wiki?
Here you have from Websters from 1913
Webster's dictionary from 1913 traces the etymology of holloa to the Old English halow and suggests "Perhaps from ah + lo; compare Anglo Saxon Heal."
The Old English verb, hlan (1. wv/t1b 1 to heal, cure, save; greet, salute; gehl! Hosanna!), may be the ultimate origin of the word. Hlan is likely a cognate of German Heil (meaning complete for things and healthy for beings) and other similar words of Germanic origin.
Bill Bryson asserts in his book Mother Tongue that "hello" comes from Old English h?l b?o ?u ("Hale be thou", or "whole be thou", meaning a wish for good health) (see also "goodbye" which is a contraction of "God be with you".

Etymology From Spanish hola, and this from Arabic wa-Allh
Hola comes from the Arabic and it means Peace be upon (with) God. This has evolved into Peace be with you, which is a very romantic and polite way of saying Hello.
Thanks for making me dig deeper.

To muddy the waters, other etymologies for hola exist. etimologias.dechile.net cites the Spanish word "Hola" as having a Classical Greek origin in (Good health, used by Homer Odyssey Chapter 24 verse 402). This Greek word appears to share PE roots with German heil which is also a greeting meaning health (cognate with English hale).
Like I said, the origin has likely traveled afar and has its root in Middle-Eastern exposure.
It is not as obvious as you make it look, runninglikezebras.
My bet is the version that is Hal (whole) + Lo with 'lo' as a call interjection morpheme. It is likely a colloquial form alike "Hail you there". "Lo" is a well known word to use to call someone's attention.
To make things worse lo may be from Old English 'la' and is not surprising if it would have a root that is influenced by Arabic primitive morphemes you "As Be" which 'la' means on a primitive level. Arabic uses 'ya' to address a person, but it does not mean the influence must be just that and Arabic is not the oldest language.
Hal-lo is still like I said an interjection which is whole + lo used to gain attention. Whole because the person is animate and lo as a way of addressing the person.
Arabic etymological search is what I am most interested in, but this was a little interesting.
By the way, 'hal' goes further back into Latin and Greek.
Please let us stop the hello topic as it gets tiring. There is no gain in proving it true or false. I think it has deeper roots than in French and I actually think the renowned lexicons that you quoted are wrong in this case. We will be stuck in recurring circular reasoning for little to gain and a waste of discussion when there are more important topics such as a proper interpretation of Quran. Let us agree to disagree on 'hello'.
Salaam
