Allah
Says:
"Say, 'we have believed in Allah and what has been revealed to us and what has been revealed to Abraham and Ishmael and Isaac and Jacob and the Descendants and what was given to Moses and Jesus and what was given to the prophets from their Lord. We make no distinction between any of them, and we are Muslims [having submitted] to Him.' So if they believe in the same way as you believe, then they have been rightly guided; but if they turn away, they are only in dissension and Allah will be sufficient for you against them. He is the Hearing, the Knowing." [Al-Baqarah (2): 136-137]
