Surah Al-Baqarah...
"And they said: 'Be Jews or Christians, you shall be guided aright'. Say: 'Nay! Rather the creed of Abraham, the upright; and he was not of those who associate partners to Allah'..." 136. "Say: 'We have believed in Allah and that which has been sent down to us, and (in) what was sent down to Abraham, Ismail, Isaac, Jacob and the tribes; and (in) that which was given to Moses and Jesus and (in) that which was given to all prophet from their Lord.
We make no distinction between any of them, and to Him do we submit'..." 137. "If then they believe in what you believe, they indeed are guided (aright); but if they turn away, then they are clearly in schism; Allah will suffice you against them; He is the All-Hearing, the All-Knowing." Occasion of Revelation Upon the occasion of revelation of these verses it is narrated from Ibn Abbas that some of the Jewish scholars and some Christians from Najran were disputing with the Muslims.
Each of these two groups considered their own creed more superior than the other's regarding the Truth, then they negated each other. The Jews said that their prophet, Moses (as), was superior and their Book, the Turah, was the best. The Christians, on the other hand, had the same claim. They said Jesus (as) was the best guide and the Evangel was the best among the heavenly Books.
Even though they could not settle their own disputes between themselves, the followers of both creeds invited the Muslims to their own religion. The above verses were revealed and answered them both. [^2] Only Our Creed is True! Egoism and self-conceit usually cause one to think that Truth is exclusively his own and therefore, he considers others wrong.
