Although some say that the big monotheistic religions all believe in the same God in different ways, I'll say it crudely like this:
Judaism and Christianity say that Islam got it wrong.
Islam and Christianity say the Jews got it wrong.
Islam and Judaism say the Christians got it wrong.
I say that they are all correct in what they say.
You state that "surly there r only one right religion", but have you considered the possibility that there is not one right religion. In other words, maybe they are all wrong?
Welcome to the wonderful world of Perennialism. Where depending on geographical location one religion claims superiority.
All religions are wrong and right at the same times because the concept of "The One True Religion" is something that is highly questionable due to subjective opinion. The one true religion is the one a person practices and that alone qualifies as truth
