2:91And when it is said to them, “Believe in what God has revealed,” they say, “We believe in what was revealed to us,” and they reject anything beyond that, although it is the truth which confirms what they have. Say, “Why did you kill God’s prophets before, if you were believers?”

2:175It is they who exchange guidance for error, and forgiveness for punishment. But why do they insist on the Fire?

2:246Have you not considered the notables of the Children of Israel after Moses? When they said to a prophet of theirs, “Appoint a king for us, and we will fight in the cause of God.” He said, “Is it possible that, if fighting was ordained for you, you would not fight?” They said, “Why would we not fight in the cause of God, when we were driven out of our homes, along with our children?” But when fighting was ordained for them, they turned away, except for a few of them. But God is aware of the wrongdoers.
