The religion and message brought by all the Prophets is undivided, all the Prophets preached the Oneness of the Creator and the divisions in religion came about through the arrogance of others. Islam is the final message sent for all peoples of the world 42:13-15
42:13 He has made plain for you the Religion with which He charged Noah and that which We have revealed to you, and that with which We charged (Prophets) Abraham, Moses and Jesus, (saying), 'Establish the Religion and do not be divided therein.' That which you invite them to is too overwhelming for the idolaters. Allah brings close to Himself whom He will, and guides to Him those who turn in repentance.
42:14 Yet they became divided only after knowledge had reached them from their own insolence. And had it not been for a Word that had preceded from your Lord, till an appointed term, it would have been determined between them. But those who inherited the Book after them are in disquieting doubt about it,
42:15 so invite and go straight as you are ordered, and do not follow their desires and say, 'I believe in whatever Book Allah has sent down. I am ordered to be just among you. Allah is our Lord and your Lord. We have our deeds and you have yours; there is no argument between us and you, Allah will bring us all together, to Him is the arrival.'
