Ask the distinguished Dr.
Norman Geisler, whose theological teachings I certainly DO recommend for study, and he'll tell you that
Allah is the personal name for God in Islam and that since both Christian and Muslim faiths believe in One supreme sovereign Creator-God, they are obviously referring when they speak of Him, under whatever terms, to the same Being.
But he'll acknowledge along with mainstream apologists that the God of
Islam is not the same as the God of Christianity for in Christianity God is a
Trinity, but in Islam God is not a Trinity. It is not possible to have God be a Trinity and also not a Trinity at the same time. Furthermore, because Islam denies the Trinity (that there is one God who is comprised of three distinct persons: Father, Son, and Holy Spirit), it means that Jesus is not the incarnation of the second person of the Trinity as God in Islam:
Quran, 5:73 (Yusuf Ali), “They do blaspheme who say:
Allah is one of three in a Trinity: for there is no god except One
Allah. If they desist not from their word (of blasphemy), verily a grievous penalty will befall the blasphemers among them.”
So it is clear that the Quran clearly denies one of the essential Christian doctrines about God’s nature so the God of Islam and the God of Christianity
are not the same even though some very smart Western theologians assert the words for God in Islam and Christianity are pointing to the same Being but through the lens of their respective epistemologies.
But ask
M. Ali and he'll say:
"Muslims use the remotest language possible to describe
Allah. They try to make him as transcendent as possible in order to discourage people from conducting research on him. If you ask a Muslim to define
Allah, he will just beat about the bush, ascribing attributes to him that neither belong to him nor befit him. But
Allah is not as mysterious as Islam would like the world to believe. He has been at the Kaaba stone all along."
He'll then go on to say that Muhammad was fascinated by the monotheistic creed of Jews and Nestorian Christians and wanted to unite the Arab race under a theocratic setting so chose one of the 360 pagan idols from his clan, specifically the one his father was named for which is
Allah and that those who try to single out
Allah and deify him above the other Meccan idols should remember that Muhammad could just as easily have picked Manaf, Al-Lat, Al-Uzza, or any of the others; and his choice didn't win the support of everyone, including his uncle, Abdul Manaf.
M. Ali says this is clear from the fact that Abdul didn't submit to
Allah and Islam until his death. He held on to Manaf. This elevation of one idol over the other 359 angered the other Meccan clans. The purported persecution of Muhammad was nothing but an inter-tribal or inter-clannish quarrel over whose idol should be or whose should not be venerated.
In the same vein, the Koran was written in Muhammads dialect (Quraish). To pacify the other tribes, Muhammad told them (with concocted revelations) that the preserved tablet in heaven was written in Quraish. The world was then asked to swallow the Islamic lie that all the Kaaba idols were destroyed. It just isnt true. About four of those idols are said to remain. The custodians of Kaaba should open the stone to independent inspectors should anyone dispute this.
Of course, there is much more to add but the point is that equating
Allah as the God of the Bible is in error. They are not the same and disagreement arises amongst theologians as to whether or not Muhammad even intended
Allah to refer to the God of the Bible from even the pure monotheistic lens of Islam.
I understand the discussion just fine friend.
Just to be fair, the Bible never claims that other religion's diety's don't exist. All it claims is that they are not God, they are just something else - demon or something most likely. So don't assume Allah doesn't exist. If you research Islam, it is a Pagan moon God but Muhammad copied from Judaism and Christianity. Just do research into it.
