The Women - 4:44
Do you not see that those who have been given a share of the Book have bought error and wish that you should go astray?
The people of the Book bought error by changing the commandments given to them according to their interests:
The Family Of Imran/3:187
"Allah had taken a promise from those to whom the Book was given, saying, "You will certainly make it clear to the people and you will not conceal it."But they threw it behind their backs and sold it for a small price. What an evil exchange!"
The Women/4:46
"Some of the Jews change the meaning of words and say, "We have heard but we do not accept,"or, "Your word falls on deaf ears,"or they twist their tongues to mock religion and say, "Raina (be our shepherd)."It would have been better and more correct for them if they had said, "We have heard and obeyed,""We are listening,"and "Watch over us."But Allah has cursed them for their disbelief. Many of them do not believe."
The Women/4:155
"Allah sealed their understanding because of their breaking their word, because they disbelieved in the signs and proofs of Allah, because they killed the prophets unjustly, and because they said: "We are fixed-minded", yes, because of their disbelief. Therefore few of them believe."
The Table Spread/5:13
We cursed them and hardened their hearts because they broke their promises. They take the meaning of words out of context. They have forgotten some of what they were warned about. From most of them you will see constant betrayal. Forgive them and ignore them. Allah loves those who do good.
The Heights/7:162
But those of them who were unjust changed the word into something other than what they were told. So We sent upon them a torment from the sky because of their wrongdoing.
