﴿ وَقَالَتِ ٱلْيَهُودُ لَيْسَتِ ٱلنَّصَٰرَىٰ عَلَىٰ شَىْءٍۢ وَقَالَتِ ٱلنَّصَٰرَىٰ لَيْسَتِ ٱلْيَهُودُ عَلَىٰ شَىْءٍۢ وَهُمْ يَتْلُونَ ٱلْكِتَٰبَ ۗ كَذَٰلِكَ قَالَ ٱلَّذِينَ لَا يَعْلَمُونَ مِثْلَ قَوْلِهِمْ ۚ فَٱللَّهُ يَحْكُمُ بَيْنَهُمْ يَوْمَ ٱلْقِيَٰمَةِ فِيمَا كَانُوا۟ فِيهِ يَخْتَلِفُونَ ﴾
“Furthermore, the Jews assert, "The Christians have no valid ground for their beliefs," while the Christians assert, "The Jews have no valid ground for their beliefs" - and both quote the divine writ! Even thus, like unto what they say, have [always] spoken those who were devoid of knowledge;" but it is God who will judge between them on Resurrection Day with regard to all on which they were wont to differ.”
Allah then mentions the claims of the Jews and Christians that their respective religion is the true Religion, saying: (And Jews) the Jews of Medina (say Christians follow nothing) as religion from God and there is no true religion except Judaism, (and Christians) the Christians of Najran (say Jews follow nothing) as religion from God and there is no true religion except Christianity; (though both are readers of the Scripture) both parties read the Book and do not believe in it and further claim things that are not mentioned therein. (Even thus spoke those who know not) knew the Oneness of Allah through their own forefathers; and it is said this means: they knew the Book of Allah from others. (Allah will judge between them) between the Jews and Christians (on the Day of Resurrection concerning that wherein they differ).
