In spite of allegations that Allah is not the same as the elohim and theos in the Bible, the use of Allah by Christians speaking Arabic and many other languages demonstrates its acceptance as a word to be used in their Bibles.
Keeping this in view, do Christians and Muslims worship the same God?
And yet, despite the manifest differences in how they practise their religions, Jews, Christians and Muslims all worship the same God. The founder of Islam, Muhammad, saw himself as the last in a line of prophets that reached back through Jesus to Moses, beyond him to Abraham and as far back as Noah.
Regarding this, what is difference between god and Allah?
Allah is usually thought to mean “the god” (al-ilah) in Arabic and is probably cognate with rather than derived from the Aramaic Alaha. All Muslims and most Christians acknowledge that they believe in the same god even though their understandings differ.
