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.

Say: Who is the Lord of the heavens and the earth?-- Say: Allah. Say: Do you take then besides Him guardians who do not control any profit or harm for themselves? Say: Are the blind and the seeing alike? Or can the darkness and the light be equal? Or have they set up with Allah associates who have created creation like His, so that what is created became confused to them? Say: Allah is the Creator of all things, and He is the One, the Supreme.

And if Allah had destroyed men for their iniquity, He would not leave on the earth a single creature, but He respites them till an appointed time; so when their doom will come they shall not be able to delay (it) an hour nor can they bring (it) on (before its time).
