Jews and Christians who believe in Allah

"And there are, certainly, among the People of the Book (Jews and Christians), those who believe in Allah, and that which has been revealed to you and in that which has been revealed to them, humbling themselves before Allah: They will not sell the Revelations of Allah for a miserable gain! For them is a reward with their Lord, and Allah is swift in account."
{Holy Quran 3:199}
