God of the Bible and God of Quran

Yes these three monotheistic faiths have common roots, I'd say that the Christians and Jews are brothers and Muslims their cousins. But history says that these three have fought amongst themselves more than any body else. Christians have mistreated the Jews from the early church to the Holocaust. Muslims Arab nations still cannot accept a Jewish nation in their neighborhood. If the God we worship is the same why can't we tolerate one and another.

Yes, and before that it was the Jews who persecuted the Christians. And in today's world across the globe it is the muslims who persecute the Christians and Jews. We're all one big dysfunctional family. Everyone wants to be the favorite.

it not just the muslim who prescute christian it,s christian prescuting christian as well.their is one belief god who leaves us instruction on how to live our lives it is man who has changed god order but god holds out a judgement for those who have change god words revelation 22:18

Needn't be sorry for your belief, it's yours!. I appreciate it. I just want to know if they different, How different they are? and is there any scripture behind it?

Sorry, but the 2 ARE the same God. Allah is just an Arabic word for God (this may or may not be common knowledge, hence your confusion)..so both religions call to 'God', just in their own language. Your viewpoint is kind of like saying French people dont believe in God because they use 'Dieu' instead of the english word 'God'. Which i'm sure you would agree is a little silly Islam, Judaism, and Christianity all believe in God, that doesnt mean that Islam is true/false or that the Quran is corect/not correct (thats beond the scope of this discussion), but that in this particular aspect of "the way" all 3 are right.
