Ans.Well that contradicts Islam because in the Quran it says that Judaism and Christianity are also religions from Allah and it is ok to follow them as they are the religions of the book (of Allah) and Jesus was the son of god in the people of the book's religion (Christianity and Judaism)and here you are saying that God has no partners etc.
As per Quran, there is no Judaism and there is no Christianity.
Quran is very clear that religions of all prophets of God was Islam. Prophets Abraham and Moses and Jesus are made to declare that they were Muslims.
That is the Quranic position on Judaism and Christianity.
But Quran says that followers of Moses and followerrs of Jesus chose different names for themselves, which were not named as such by their prophets.
Quran invites followers of all prophets to join and follow the Last and Final prophet to unite and make a common front.
But if they refuse to accept Final Prophet, then let them atleast faithfully follow the true teachings of their own prophets (with the hope and strong chances that once they do that, they would very soon accept the teachings of Last prophet, because they are in fact continuation of teachings of their prophets), and try to excell each other in doing more and more good deeds.
So the cliamte should be less of arguments and conflict and each one trying to :prove that their religion is best. Let Allah decide on the last day, who followed true path and who was in the error.
This is called broadmindedness and tolerance of Islam. Asking people to have less discussions and more actions.
Allah Knows Best.
