Surah Aal-i-Imraan, Verse 199
وَإِنَّ مِنْ أَهْلِ ٱلْكِتَٰبِ لَمَن يُؤْمِنُ بِٱللَّهِ وَمَآ أُنزِلَ إِلَيْكُمْ وَمَآ أُنزِلَ إِلَيْهِمْ خَٰشِعِينَ لِلَّهِ لَا يَشْتَرُونَ بِـَٔايَٰتِ ٱللَّهِ ثَمَنًۭا قَلِيلًا ۗ أُو۟لَٰٓئِكَ لَهُمْ أَجْرُهُمْ عِندَ رَبِّهِمْ ۗ إِنَّ ٱللَّهَ سَرِيعُ ٱلْحِسَابِ
Translation — Sahih International
And indeed, among the People of the Scripture are those who believe in Allah and what was revealed to you and what was revealed to them, [being] humbly submissive to Allah. They do not exchange the verses of Allah for a small price. Those will have their reward with their Lord. Indeed, Allah is swift in account.
