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.

Say: Tell me if the chastisement of Allah should overtake you or the hour should come upon you, will you call (on others) besides Allah, if you are truthful?

Say: Have you considered your associates which you call upon besides Allah? Show me what part of the earth they have created, or have they any share in the heavens; or, have We given them a book so that they follow a clear argument thereof? Nay, the unjust do not hold out promises one to another but only to deceive.

Say: Have you considered what you call upon besides Allah? Show me what they have created of the earth, or have they a share in the heavens? Bring me a book before this or traces of knowledge, if you are truthful.
