The followers of the Book ask you to bring down to them a book from heaven; so indeed they demanded of Musa a greater thing than that, for they said: Show us Allah manifestly; so the lightning overtook them on account of their injustice. Then they took the calf (for a god), after clear signs had come to them, but We pardoned this; and We gave to Musa clear authority.

And they ask you to hasten on the chastisement; and had not a term been appointed, the chastisement would certainly have come to them; and most certainly it will come to them all of a sudden while they will not perceive.
