15. After the introductory (verses 1-10), the Quran takes up admonition which is the main subject of the Surah. In order to understand this fully we should keep two things in view as its background:
First, a little before its revelation, the continuous horrible famine, which had afflicted Makkah for seven long years and humbled the haughty Quraish, had come to an end. Naturally this had given a blow to idol worship and acted as a stimulus to God worship. For, in their utter helplessness, they had to supplicate to Allah and cry meekly for help. So much so that Abu Sufyan had to approach the Prophet (peace be upon him) with this request: Please pray to Allah to remove this affliction from us. But when the famine was over, and rains began to fall, and prosperity returned, they began to show rebellion and do evil deeds and started their hostile activities against the believers. Thus the hearts that had turned to Allah, again became neglectful of Him. See (Surah An-Nahal, Ayat 113), (Surah Al-Mominoon, Ayats 75-77), (Surah Ad-Dukhan, Ayats 10- 16).
Secondly, the Quran answered the question with which they confronted the Prophet (peace be upon him) whenever he warned them of the consequences of rejecting the truth. They would say” You are always threatening us with Allah’s wrath; why doesn’t the divine torment visit us and why is it being delayed?
Keeping the above background in view, (Ayats 11-12 )may be expanded like this: Allah does not hasten in punishing and seizing the people for their sins as He hastens in showing kindness and compassion to them. Do they, then, want Him to hasten His torment for their rebellions, as He hastened to remove famine in answer to their supplications? As this is not Our Way, We give them time to mend their evil ways in spite of their transgressions and rebellions. We send warning after warning and give them respite until their term comes to an end. Then the law of requital comes into force. In contrast to this, their way is the way of mean and narrow minded people. When affliction comes, they remember Allah, begin to cry and call Him meekly, but forget it all during the time of prosperity. Such bad ways as these are leading them to divine torment.
16. The Arabic word qarn is commonly used for the people living during the same period. But from the way the Quran has used this word on different occasions, it is evident that by qarn is, meant the community which had been invested with power and authority and appointed wholly or partially to the position of leadership of the world. One way in which such a community is destroyed is that it is totally exterminated but there are other forms of its destruction also.
17. Here the word zulm has not been used in its commonly known limited sense, but it covers all sorts of sins that are committed, when people transgress the boundaries of Allah’s slavery. Refer to (E.N. 49 of Surah Al-Baqarah).
18. (Ayats 13-14) have been pointedly addressed to the Arabs so as to say, “O Prophet (peace be upon him) of Arabia, learn a lesson from the communities that have passed before you. They were given an opportunity for doing good deeds in their time but instead of this they adopted the attitude of transgression and rebellion and rejected the teachings of the Messengers who had been sent for their guidance. As they failed in Our test, We dismissed them from leadership. Now, O people of Arabia, your turn has come and you have replaced them and have gotten the opportunity for doing the same work under the guidance of Our Prophet Muhammad (peace be upon him). You must understand that you are undergoing the same test in which your predecessors have failed. If you do not want to meet with the end they met, you should make the right use of this opportunity by learning a lesson from their end and by avoiding the errors, which became the ultimate cause of their destruction.
