أَلَمْ يَرَوْا۟ كَمْ أَهْلَكْنَا مِن قَبْلِهِم مِّن قَرْنٍۢ مَّكَّنَّٰهُمْ فِى ٱلْأَرْضِ مَا لَمْ نُمَكِّن لَّكُمْ وَأَرْسَلْنَا ٱلسَّمَآءَ عَلَيْهِم مِّدْرَارًۭا وَجَعَلْنَا ٱلْأَنْهَٰرَ تَجْرِى مِن تَحْتِهِمْ فَأَهْلَكْنَٰهُم بِذُنُوبِهِمْ وَأَنشَأْنَا مِنۢ بَعْدِهِمْ قَرْنًا ءَاخَرِينَ
See they not how many a generation We destroyed before them, whom We had established in the earth more firmly than We have established you, and We shed on them abundant showers from the sky, and made the rivers flow beneath them. Yet we destroyed them for their sins, and created after them another generation.
