(6) أَ لَمْ يَرَوْا كَمْ أَهْلَكْنا مِنْ قَبْلِهِمْ مِنْ قَرْنٍ مَكَّنَّاهُمْ فِي الْأَرْضِ ما لَمْ نُمَكِّنْ لَكُمْ وَ أَرْسَلْنَا السَّماءَ عَلَيْهِمْ مِدْراراً وَ جَعَلْنَا الْأَنْهارَ تَجْرِي مِنْ تَحْتِهِمْ فَأَهْلَكْناهُمْ بِذُنُوبِهِمْ وَ أَنْشَأْنا مِنْ بَعْدِهِمْ قَرْناً آخَرِينَ
6. " Have they not considered how many a generation We destroyed before them, whom We had established in the earth (to the extent) that We have not established you, and We sent abundant (water down from) the sky upon them and made the rivers flow beneath them ? Yet We destroyed them for their sins, and raised up after them another generation."
We must take an example from the history and fate of others.
This style is one of the training methods of the Qur'an by which it states some factual and teaching stories.
The retribution of those who abuse the divine facilities given to them in this world, is destruction.
Besides the chastisement in the Hereafter, Allah punishes the sinners in the present world, too.
The powerful people should not think that they are always in comfort in the world. The Lord punishes them and substitudes some others in their place.
Thus, the cause of all inflictions are people's own deeds.
The Qur'anic term /qarn/ is used for calling a community who had been utterly destroyed so that none of them remained after them, (cited in Aqrab-ul-Mawarid) .
All people who live comtemporarily are also called in Arabic /qarn/. They are usually a generation living a length of time about 60 years or 80 years or 100 years. (cited in commentary books entitled Almizan, and Tafsir-ul-Kabir, by Fakhr-i-Razi)
