The Cow - 2:91
"When it is said to them, "Believe in what Allah has sent down,"they say, "We believe in what has been sent down to us,"and deny what follows. But this is the truth confirming what is with them. Say, "Why did you kill the messengers of Allah before, if you believed?"
Do all the people of the Book believe only in what has been sent down to them?
The Family Of Imran/3:113
But not all of them are one. There is a righteous group from among the people of the Book who recite the verses of Allah at night and prostrate themselves.
The Family Of Imran/3:114
They believe in Allah and the Last Day, and they exhort to good and forbid evil and do good deeds. They are of the righteous.
The Spider/29:47
This is the Book We have sent down to you. Those to whom We have given the Book will believe in it, and some of them will believe. None rejects Our Verses except the unbelievers.
The Family Of Imran/3:199
Among the People of the Book are those who believe in Allah and what has been sent down to you and what has been sent down to them. They have deep respect for Allah. They do not sell the Verses of Allah for a small price. Their reward is with their Lord. Allah is quick in reckoning.
