6:6
أَلَمْ يَرَوْا۟ كَمْ أَهْلَكْنَا مِن قَبْلِهِم مِّن قَرْنٍ مَّكَّنَّـٰهُمْ فِى ٱلْأَرْضِ مَا لَمْ نُمَكِّن لَّكُمْ وَأَرْسَلْنَا ٱلسَّمَآءَ عَلَيْهِم مِّدْرَارًا وَجَعَلْنَا ٱلْأَنْهَـٰرَ تَجْرِى مِن تَحْتِهِمْ فَأَهْلَكْنَـٰهُم بِذُنُوبِهِمْ وَأَنشَأْنَا مِنۢ بَعْدِهِمْ قَرْنًا ءَاخَرِينَ
Have they not seen how many generations We destroyed before them which We had established upon the earth as We have not established you? And We sent [rain from] the sky upon them in showers and made rivers flow beneath them; then We destroyed them for their sins and brought forth after them a generation of others.
