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.

But whoever disputes with you in this matter after what has come to you of knowledge, then say: Come let us call our sons and your sons and our women and your women and our near people and your near people, then let us be earnest in prayer, and pray for the curse of Allah on the liars.

Do not hold the Messenger's calling (you) among you to be like your calling one to the other; Allah indeed knows those who steal away from among you, concealing themselves; therefore let those beware who go against his order lest a trial afflict them or there befall them a painful chastisement.
