noone denies that the arabic speaking jews and christians spoke arabic.
it's fairly realistic to assume that they translated the word Elah to arabic root words like Alaha of whatever.
Has nothing to do with Islam, Christians worshipped Allah before Muhammed came on the scene and perverted the name God into his perverted perspective.
Yet what has an arabic speaking christians or jews who translated it from the hebrew, greek and possibly aramaec to do with the name of God as described in the Torah and revealed in the Gospels.
of course Arabic will find resemblances in ancient Arabic, that's only logical. What Allah does not resemble is Yehovah, the name of God.
Not by root words and not by translations.
no matter how long you'll ever beat around the bush, this will never change
