(Qur'an...
(Qur'an, 5:44) The Qur'an reveals that some Jewish scholars and rabbis "distorted words from their proper meanings" in the Torah (Qur'an, 5:41) and falsified it: "Woe to those who write the Book with their own hands and then say: 'This is from God,' to sell it for a paltry price" (Qur'an, 2:79). Christians, on the other hand, made a grave mistake by deifying Jesus (pbuh) Qur'an, 4:171).
However, God's revelation of such mistakes does not mean that the People of the Book are in complete ignorance and error, for He also reveals that some of them are deeply religious and devoted to God: 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) Therefore, a Muslim's attitude toward the People of the Book reflects the probable existence of genuinely faithful people among them. Only God knows the hearts of people, and He reveals that some Jews and Christians have earned His good pleasure. Prophet Abraham (pbuh) Was a Haneef God reveals that He has created a way and a method for all nations. Throughout history, He has sent Prophets to people to inform them of His laws, commands, and prohibitions.
Essentially, all Prophets have invited their nations to believe in and worship God and to abide by the limits He has established for humanity. In other words, all true religions in their original state are based on the principles of not associating others with Him and of working to win His good pleasure, compassion, and Paradise. All nations are expected to follow God's will without fail and to do good deeds in order to earn His reward: We have appointed a law and a practice for every one of you.
Had God willed, He would have made you a single community, but He wanted to test you regarding what has come to you. So, compete with each other in doing good.
