Really, many people claim that Allah is just an Arabian term for
God. Actually, it is. But it's not that simple, see? The dictionaries are all about different meanings. So: Common meaning in this time in non-arabic countries is that it reffers to the Moslim
God, who IS different - at least the moslim's view is really different from Christians' and Jews'! Christians believe, that Jesus is
God, Jews don't take Him at all, Moslims don't take him as
God but just as one of the prophets. So - the Christians'
God is not the same as Moslims' - He is Jesus, who sacrificed and resurrected - I am not Jew but I think their view of
God is really different, too.
