Remember, when Abraham said: “O Lord, show me how you raise the dead,” He said: “What! Do you not believe?” “I do,” answered Abraham. “I only ask for my heart’s assurance.” (The Lord) said: “Trap four birds and tame them, then put each of them on a (separate) hill, and call them, and they will come flying to you. Know that God is all-powerful and all-wise.”
