The Cow - 2:64
But after that you turned away. Had it not been for Allah´s bounty and mercy upon you, you would have lost.
How did the Children of Israel turn away?
The Cow/2:83
We took a promise from the Children of Israel: You shall serve none but Allah, and you shall do good to parents and relatives and orphans and the poor. You shall speak to people in friendship. You will observe the prayer and pay the zakat. But after that you turned away, except a few of you.
The Cow/2:84
We had also taken a promise from you that you would not shed each other´s blood and would not drive each other out of their homes. You had accepted this and were witnesses to it.
The Cow/2:85
After all this, you still kill one another and drive out a group of you from their homes and unite against them in evil and enmity. It is already forbidden for you to drive them out of their homes, and as if that were not enough, when they are captured by you, you demand ransom from them. Or do you believe in part of the Book and disbelieve in part of it? What is the recompense for those who do so but disgrace in the life of this world and the harshest of torments on the Day of Resurrection? Allah is not heedless of what you do.
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 Cow/2:93
"Remember when We raised Mount Tur over you and took a promise from you: "Hold fast to what I command you and listen."But they said: "We listened and disobeyed". Because of their disbelief, their hearts were deceived by the calf. Say: "If you have believed, how badly your faith is guiding you!"
The Women/4:154
"We raised Mount Sinai above them, and We said to them, "Enter humbly through the gate."We said to them, "Do not transgress the prohibition of Saturday"; and We took from them a firm promise."
