Have you not considered him (Namrud) who disputed with Ibrahim about his Lord, because Allah had given him the kingdom? When Ibrahim said: My Lord is He who gives life and causes to die, he said: I give life and cause death. Ibrahim said: So surely Allah causes the sun to rise from the east, then make it rise from the west; thus he who disbelieved was confounded; and Allah does not guide aright the unjust people.

And when Ibrahim said: My Lord! show me how Thou givest life to the dead, He said: What! and do you not believe? He said: Yes, but that my heart may be at ease. He said: Then take four of the birds, then train them to follow you, then place on every mountain a part of them, then call them, they will come to you flying; and know that Allah is Mighty, Wise.
