I believe so...
The "prophet" Muhammad said " that according to Allah "the most awful name on the day of resurrection will be the name of a man calling Himself "King of kings"
Sahih-hal Bukhari Bk 73 Num: 224
"Awful" Why awful? Because according to Revelations the son of man will return with the words "King of kings" on his thigh and Satan will be cast into the lake of fire.
According to Islam God does not have a son yet Allah knows who Jesus is and dreads His return.
I've read that there is a pre-Islamic Arabic inscription in a cave that refers to God as 'Allah.' Prior to Islam, there was a St. Abdullah (contraction of Abdu- Allah, which means servant of Allah) who was a slave who brought the Gospel to the Arabs. Abdullah was a popular baptism name for Christians. We don't have any pre-Islamic Arabic liturgies or Bible translations from the pre-Muhammad era from what I've read. But the evidence seems to point to the idea that Christians used the word.
The derivation of 'Allah' that I've read, and I think Arabic philologists accepted this, was that it was supposed to come from a contracted form (which doesn't follow regular grammatical rules like the contraction Abdullah) of Al illah.
Al means 'the' and 'ilah' means 'god.' In some NT verses in Greek, God is referred to as 'the God' though the definite article is rarely translated.
'Ilah' is believed to be cognate with the Hebrew 'Eloah, the singular of 'Elohim. You can see a lot of cognate words across Semitic languages. They will often share the same three consonants. If I recall correctly, the word for 'night' is cognate between these two language. Also, the word for 'book' or 'scribe' is cognate across Arabic and Hebrew. In the case of 'Ilah and 'Eloah, the trilateral root would be 'LH, with ' signifying a glottal stop, and it's a letter in both languages (aleph.)
(English speakers can't usually recognize glottal stops without some training, especially in the initial position. Just imagine a Cockney English person saying "ho' wa'er bo'l" instead of 'hot water bottle.)
Anyway, my point is that 'Allah is likely the pre-Islamic Christian word for God. It is the word for God used by many Arabic speakers and Indonesian speakers. If you belong to a denomination that has a church in Indonesia, those churches likely call God 'Allah. If you go to a Church of Christ, there are missionaries and local people in the Sidang Jemat Kristus, that call God Allah. If you go to an Assembly of God, well in Indonesia, it's Sidang Jemat Allah. You can go to a Baptist church and hear about Jesus the Son of 'Allah. The Roman Catholics use the word, too.
If you went to church in Indonesia and asked if 'Allah was Satan, you'd be asking if God was Satan. Maybe the ushers would escort you out. Some Indonesian Christians might refer to 'their allah' when talking about Muslims beliefs about God--'Allahnya mereka...."
There is one preacher who was preaching against using 'Allah and a translation that substituted 'Elohim was used to replace it. If it were me, I'd get rid of the word 'Tuhan.' It's another word that means 'God', but they substitute it for kurious ("Lord") in translation. So when Jesus asks the man born blind if he believes on the Son of God, he responds, "Who is he, God, that I might believe in Him?" I believe the first word is "Allah" and the second is "Tuhan", but that's how it translates back into English. That's a bigger problem for the translation than getting rid of the word Allah in my opinion.
Malaysians speak nearly the same language, but Muslims won't allow Christians to use Allah in their translations, but they have a much smaller population.
