102. This may also mean: To send down one commandment to elaborate upon the other, for the commandments were sent down piecemeal in the Quran. For instance, the commandments about prohibition and fornication were sent down gradually one after the other during several years. But We hesitate to accept this interpretation because An-Nahl is a Makki Surah and to the best of our information there is no instance to show that commandments were sent down piecemeal at Makkah. Therefore, we prefer the other interpretation. The Quran has added details of one theme and explained the same with different kinds of illustrations at different places. Likewise it has related a story in different words at different places and presented its different aspects and details at other places. It has put forward one argument at one place to prove a theme and another at another place to prove the same theme. It has related one theme concisely at one place and in detail at the other. That is what the disbelievers of Makkah put forward as proof that Muhammad (peace be upon him) forged the Quran himself. They argued like this: Had the Quran been the Word of Allah, it would have related one thing in full at one place, for Allah’s knowledge is not defective that He should have to think out gradually the details of a theme and to give different versions to explain the same thing. In contrast to this, the knowledge of a human being is defective. A man has to think out gradually as has been done in the case of the Quran which is a clear proof that you have forged it yourself.

103. The Holy Spirit: Gibril. Instead of using the name of the angel who brought revelation, his title has been deliberately mentioned to warn the disbelievers that the Holy Spirit who brought revelation is free from human frailties. He is neither dishonest that he should add something to or take away something from the message he brought, nor is he a liar and forger that he should invent and state something in the name of Allah. Nor does he suffer from any human lust that he should practice a deceit. He is wholly pure and holy and conveys the Word of Allah intact.

104. That is, the fact that Allah sends down His message piecemeal does not mean that Allah’s knowledge and wisdom are defective as you consider because of your folly. Allah sends His revelations gradually because human intelligence and capacity to grasp are limited and defective which do not let him understand the whole theme at one and the same time and make it firm in his mind. Therefore, Allah in His wisdom conveyed His revelation piecemeal through the Holy Spirit. He sends a theme gradually and gives its details by and by and uses different methods and ways to make it plain to human beings so that they might grasp it according to their abilities and capabilities and become firm in their faith and knowledge.

105. The second practical wisdom of sending down the Quran piecemeal was that those believers who obediently followed it, should get necessary instructions for the propagation of Islam and the solution of other problems of life at the time when they were actually needed. It is obvious that if those instructions had been sent down before time and at one and the same time they would not have been useful.

106. The third practical wisdom of not sending down the Quran as a whole at one and the same time was to give good tidings and encouragement to the obedient servants who were suffering from persecution and encountering great obstacles because they needed it over and over again. That is why they were assured of ultimate success time and again to fill them with hope to carry on their mission.
