I refer to the letter 'God', 'Jesus' not the same thing in Christianity .
The word 'Allah' has a very special meaning in its original language, Arabic, and it has such attributes, one of which is 'a super natural being that is not begotten nor begets'.
If Christians belief that Jesus is the only begotten Son of God then the usage of the word Allah to denote God in the Bible cannot be true of the word 'Allah' in its Arabic context.
