And when Abraham said, 'My Lord, show me how Thou wilt give life to the dead,' He said, 'Why, dost thou not believe?' 'Yes,' he said, 'but that my heart may be at rest.' Said He, 'Take four birds, and twist them to thee, then set a part of them on every hill, then summon them, and they will come to thee running. And do thou know that God is All-mighty, All-wise.'
