There have been conflicts and disputes between members of these three religions in the past, but those were the result of the erroneous reasoning and evil motives of certain states, nations, and individuals who pursued their own economic and political gain instead of the central beliefs of Judaism, Christianity, and Islam. One of the common aims of these divinely revealed religions is to ensure the happiness, security, peace, and tranquility of all people by opposing conflict.
<b>Say: "O People of the Book! Come to a proposition that is the same for us and you-that we should worship none but God, not associate any partners with Him, and not take one another as lords besides God." If they turn away, say: "Bear witness that we are Muslims." (Qur'an, 3:64)</b>

He has sent down the Book to you with truth, confirming what was there before it. And He sent down the Torah and the Gospel. (Qur'an, 3:3-4)
We sent down the Torah containing guidance and light, and the Prophets who had submitted themselves gave judgment by it for the Jews?as did their scholars and their rabbis?by what they had been allowed to preserve of God's Book, to which they were witnesses. (Qur'an, 5:44)
They are not all the same. There is a community among the People of the Book who are upright. They recite God's Signs throughout the night, and they prostrate. They believe in God and the Last Day, enjoin the right and forbid the wrong, and compete in doing good. They are among the righteous. You will not be denied the reward for any good thing you do. God knows those who guard against evil. (Qur'an, 3:113-15)
Among the People of the Book are some who believe in God and in what has been sent down to you and what was sent down to them, and who are humble before God. They do not sell God's Signs for a paltry price. Such people will have their reward with their Lord. And God is swift at reckoning. (Qur'an, 3:199)
