I often hear people say, there is only one God and Islam worships the same God as Christians. I disagree but I am not sure I have the right answer. If our God had a Son who died for our Sins and His name was Jesus Christ, and their god didn’t have that same Son who died for their sins, how can anyone say we worship the same God?
The idea that God and Allah are the same is a politically correct opinion that can neither be supported in the Bible nor in the Qur’an. Jesus is considered to be a messenger of Allah in the Qur’an, but is not the son of God and certainly not deity. Qur’an 112:3 states that God (Allah) begets not, nor is he begotten.
Saying the God of Christianity and the God of Islam are the same is like two men who both claim to know the same person, but when they start comparing their knowledge of the person they soon realize that although they both call him by the same name they are actually describing two different people.
Comparing what the Bible says about God with what the Qur’an says about Allah will bring you to the same conclusion.
