Call to mind the other event also, when Abraham said, "My Lord, show me how Thou bringest the dead back to life?" He said "Have you no faith in this?" Abraham humbly replied, "I do believe but I ask this to reassure my heart." Allah said, "Well, take four birds and tame them with yourself and then (cut them into pieces) and place a piece of each of them on each hill. Then call them and they will come running to you; know this for certain that Allah is All-Powerful, All-Wise."
