﴿ وَقَالُوا۟ كُونُوا۟ هُودًا أَوْ نَصَٰرَىٰ تَهْتَدُوا۟ ۗ قُلْ بَلْ مِلَّةَ إِبْرَٰهِۦمَ حَنِيفًۭا ۖ وَمَا كَانَ مِنَ ٱلْمُشْرِكِينَ ﴾
“AND THEY say, "Be Jews" - or, "Christians" - "and you shall be on the right path." Say: "Nay, but [ours is] the creed of Abraham, who turned away from all that is false, and was not of those who ascribe divinity to aught beside God."”
Allah mentioned after this the dispute of the Jews and Christians with the believers, saying: (And they say) i.e. the Jews: (Be Jews) you shall be guided from error (or Christians) and the Christians also say the same, (then ye will be rightly guided. Say) to them, O Muhammad: it is not as you claim: (Nay, but the religion of Abraham, the upright) the Muslim; rather follow the religion of Abraham, the upright, the Muslim, the sincere-only then you will be guided, (and he was not of the idolaters) i.e. he did not follow the religion of the Jews or Christians.
