All Prophets and Messengers were sentwith one Message. God says: "Or have they taken gods besides Him?Say, O Muhammad to them], 'Produceyour proof. This Qur'an] is the messagefor those with me and the message ofTHE GREATPROPHETSOF GODthose before me.' But most of them donot know the truth, so they are turningaway. And We sent not before you anymessenger except that We revealed tohim that, 'There is no deity except Me, so worship Me.'" (Qur'an 21:24-25)The belief in the Oneness of God wasthe central message delivered by allProphets and Messengers to theirrespective peoples. God, the Exalted, says: "He has ordained for you of religionwhat He enjoined upon Noah and thatwhich We have revealed to you, OMuhammad], and what We enjoinedupon Abraham and Moses and Jesus -to establish the religion and not bedivided therein. Difficult for those whoassociate others with Allah is that towhich you invite them. Allah chooses forHimself whom He wills and guides toHimself whoever turns back to Him]."(Qur'an 42:13)
