Surah 2. Al-Baqara
Ayah 260
260وَإِذْ قَالَ إِبْرَٰهِـۧمُ رَبِّ أَرِنِى كَيْفَ تُحْىِ ٱلْمَوْتَىٰ ۖ قَالَ أَوَلَمْ تُؤْمِن ۖ قَالَ بَلَىٰ وَلَـٰكِن لِّيَطْمَئِنَّ قَلْبِى ۖ قَالَ فَخُذْ أَرْبَعَةً مِّنَ ٱلطَّيْرِ فَصُرْهُنَّ إِلَيْكَ ثُمَّ ٱجْعَلْ عَلَىٰ كُلِّ جَبَلٍ مِّنْهُنَّ جُزْءًا ثُمَّ ٱدْعُهُنَّ يَأْتِينَكَ سَعْيًا ۚ وَٱعْلَمْ أَنَّ ٱللَّهَ عَزِيزٌ حَكِيمٌ
[260] 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."296 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."297
296That is, "I want that peace of mind which is gained by actual experience. "
297Some people have offered strange interpretations for the two abovementioned extraordinary events. But there is no need to make far-fetched interpretations, for Allah is able to do everything He wills, as the person referred to in the first event declared. Moreover, Allah's dealings with His Prophets are of an extraordinary nature; for an ordinary believer does not need to see actually the Reality with his own eyes for the performance of his duties but it is essential for the mission of a Prophet that he should see with , his own eyes those realities towards which he has to invite the people. The Prophets have to tell the people with full and firm conviction: "We have seen with our own eyes those realities about which your knowledge is based on mere guess-work. You are ignorant; but We possess knowledge; you are blind, but We possess sight." That is why the angels came to them in person so that they should see them with their own eyes. They were also shown the actual working of the system of the heavens and the earth, and Paradise and Hell and Resurrection after death. Though the Prophets believed in all these things even before their appointment as Messengers, they were made witnesses of the realities after their appointment as a special favour and distinction of prophethood. (For further reference, please see E.N.'s 17, 18, 19, 34 of Surah Hud, Xl).
