Surah Al-Ma'idah, Verse 68

قُلۡ يَٰٓأَهۡلَ ٱلۡكِتَٰبِ لَسۡتُمۡ عَلَىٰ شَيۡءٍ حَتَّىٰ تُقِيمُواْ ٱلتَّوۡرَىٰةَ وَٱلۡإِنجِيلَ وَمَآ أُنزِلَ إِلَيۡكُم مِّن رَّبِّكُمۡۗ وَلَيَزِيدَنَّ كَثِيرٗا مِّنۡهُم مَّآ أُنزِلَ إِلَيۡكَ مِن رَّبِّكَ طُغۡيَٰنٗا وَكُفۡرٗاۖ فَلَا تَأۡسَ عَلَى ٱلۡقَوۡمِ ٱلۡكَٰفِرِينَ٦٨

qul yāahla l-kitābi lastum ʿalā shayin ḥattā tuqīmū l-tawrāta wal-injīla wamā unzila ilaykum min rabbikum walayazīdanna kathīran min'hum mā unzila ilayka min rabbika ṭugh'yānan wakuf'ran falā tasa ʿalā l-qawmi l-kāfirīna

Say, "O People of the Scripture, you are [standing] on nothing until you uphold [the law of] the Torah, the Gospel, and what has been revealed to you from your Lord [i.e., the Qur’ān]." And that which has been revealed to you from your Lord will surely increase many of them in transgression and disbelief. So do not grieve over the disbelieving people.
