Perhaps I phrased that wrong. The name in question, is one that refers very often to Deity in the Torah and Hebrew Bible. Because I haven't found it to resemble any of the Islamic names for Allah, I wonder: Why is it so important to the Jews? they consider it a personal name for the Deity? And I find no corresponding personal name in Islam, in terms of similar word structure - as I have been told - Allah, if any, is The personal name - Faizah is correct, Allah in word form does not seem to resemble the Tetragrammaton (four-letter-word). But since the Quran says that Allah sent the Torah and Gospel, I am complelled to a degree to think that the name in question reffers to him - BUT, I am somewhat cautious, I understand that corruption can certainly be present in the Hebrew we see today - someone could possibly have added that to the text. I don't know what the differences are between the Torah we see today and the Torah given to Moses. But if this name arose out of corruption it would be a huge corruption, given its frequency of use. I see the point of that reference you gave, Faizah: if its not in the Sunnah, how would we know for certain? It's then best to assume its not to be used out of caution.

My question is basically - what is the Islamic stance on that name? Is it just an unknown phenomenon?

It's hard for me to believe there hasn't been any deep scholarly debate on this issue. I'm curious to know if anyone has found one or more.
