Surah Ali'Imran, Verse 199

وَإِنَّ مِنۡ أَهۡلِ ٱلۡكِتَٰبِ لَمَن يُؤۡمِنُ بِٱللَّهِ وَمَآ أُنزِلَ إِلَيۡكُمۡ وَمَآ أُنزِلَ إِلَيۡهِمۡ خَٰشِعِينَ لِلَّهِ لَا يَشۡتَرُونَ بِـَٔايَٰتِ ٱللَّهِ ثَمَنٗا قَلِيلًاۚ أُوْلَٰٓئِكَ لَهُمۡ أَجۡرُهُمۡ عِندَ رَبِّهِمۡۗ إِنَّ ٱللَّهَ سَرِيعُ ٱلۡحِسَابِ١٩٩

wa-inna min ahli l-kitābi laman yu'minu bil-lahi wamā unzila ilaykum wamā unzila ilayhim khāshiʿīna lillahi lā yashtarūna biāyāti l-lahi thamanan qalīlan ulāika lahum ajruhum ʿinda rabbihim inna l-laha sarīʿu l-ḥisābi

And indeed, among the People of the Scripture are those who believe in Allāh and what was revealed to you and what was revealed to them, [being] humbly submissive to Allāh. They do not exchange the verses of Allāh for a small price. Those will have their reward with their Lord. Indeed, Allāh is swift in account.
