وَاِنَّ مِنْ اَهْلِ الْكِتٰبِ لَمَنْ يُّؤْمِنُ بِاللّٰهِ وَمَآ اُنْزِلَ اِلَيْكُمْ وَمَآ اُنْزِلَ اِلَيْهِمْ خٰشِعِيْنَ لِلّٰهِ ۙ لَا يَشْتَرُوْنَ بِاٰيٰتِ اللّٰهِ ثَمَنًا قَلِيْلًا ۗ اُولٰۤىِٕكَ لَهُمْ اَجْرُهُمْ عِنْدَ رَبِّهِمْ ۗ اِنَّ اللّٰهَ سَرِيْعُ الْحِسَابِ ( آل عمران: ١٩٩ )
Wa inna min Ahlil Kitaabi lamai yu minu billaahi wa maaa unzila ilaikum wa maaa unzila ilaihim khaashi 'eena lillaahi laa yashtaroona bi Aayaatil laahi samanan qaleelaa; ulaaa'ika lahum ajruhum 'inda Rabbihim; innal laaha saree'ul hisaab (ʾĀl ʿImrān 3:199)
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. (Ali 'Imran  : 199)

Surely, among the people of the Book there are those who believe in Allah, and in what has been sent down to you and what has been sent down to them, humbling themselves before Allah. They do not barter away the verses of Allah for paltry (worldly) gains. They have their reward with their Lord. Surely, Allah is swift at reckoning.
