Important Words:
رتلناہ ترتیلا (We arranged it in the best form) is derived from رتل (ratala). They say رتل الشیء i.e. the thing was or became well arranged. رتل الکلام (rattala) means, he put together and arranged well the component parts of the speech or saying and made it distinct. ترتیل (inf. noun) in its original sense relates to the teeth, their being separate one from another. The addition of the infinitive to the verb رتلنا is done in order to intensify the sense (Lane).
Commentary:
The Quran was revealed piecemeal and at intervals. This was intended to serve two very useful purposes: (i) The interval between the revelation of different passages afforded the believers an opportunity to witness fulfilment of some of the prophecies made in the passages already revealed and thus their faith became strengthened and fortified. Further it was intended to answer the objections raised by disbelievers during the interval. (ii) When Muslims needed guidance on a particular occasion to meet a particular need, necessary and relevant verses were revealed. Besides, the revelation of the Quran was spread over a period of 23 years in order to enable the Companions of the Holy Prophet to remember, learn and assimilate it. Moreover, the Quran had anticipated one possible objection of disbelievers and its gradual revelation was intended to answer that objection. If it had been revealed at once and in the form of one complete book, the disbelievers could have said that the Holy Prophet had got it all prepared from somebody. Thus its gradual revelation at different times, on different occasions and under vastly different conditions and circumstances, effectively smashed this possible objection. Last of all there was a prophecy of Prophet Isaiah that the last Divine Book would be revealed piecemeal and at intervals. The prophecy is as follows:
"Whom shall he teach knowledge and whom shall he make to understand the message? them that are weaned from the milk, and drawn from the breast? For it is precept upon precept; precept upon precept, line upon line, line upon line; here a little and there a little: for with strange lips and another tongue will he speak to this people" (Isaiah 28: 9-10).
The words, "We have arranged it in the best form," signify that whereas the Quran was revealed gradually and piecemeal to meet the needs of changing circumstances, it did not remain a collection of disorderly fragments but was given a perfect order and arrangement by Divine revelation. It may be noted here that the present order of the Quran is different from that in which it was originally revealed. It was revealed in an order which suited the needs and requirements of its immediate addressees and was arranged, under Divine direction, in an order which suited the permanent needs of humanity at large. Since both these kinds of needs were different, the two orders should necessarily have been different. It is indeed an outstanding miracle of the Quran that it was revealed in an order which was best suited for the needs of the period during which it was revealed and was arranged for permanent use in the order which was also best suited for humanity’s lasting needs.
