What Is With Them

S 2:89 And when a book came to them from Allah confirming what is with them, and they used to ask before for victory over those who disbelieved, so when what they knew came to them, they disbelieved in it. So Allah’s curse is on the kafirun.

S 2:91 And when it was said to them: Believe in what Allah has sent down, they said: We believe in what was sent down upon us. And they disbelieve in what is behind it, and it is the truth confirming what is with them. Say: So why do you kill Allah’s prophets before, if you are believers?

S 2:101 And when a messenger came to them from Allah confirming what is with them, a party of those who were given the Book chucked Allah’s book behind their backs as though they do not know.

A similar one is S 3:81

And when Allah took the covenant of the prophets: What I have given you of a book and wisdom then a messenger has come to you confirming what is with you, you shall believe in him and help him. He said: Have you ratified and taken my compact upon that? They said: We have ratified. He said: Then bear witness and I am with you among the witnesses.
