The people of the scripture will ask you to perform a miracle and ask God to send down a divine book from the heaven [as a proof to your claim for prophet hood.] Never mind them as these are the same people who asked Moses for even greater miracle. They said: “Show us God in person.” They [naturally could not stand the presence of the Lord and] were caught by thunder and lightening for their audacity. In spite of all that, they turned into cow worshipping! [This proves that no miracle can change their behavior/ attitude.] Even so I forgave them and blessed Moses with the most amazing miracles.
