Taha Ayah 128

أَفَلَمْ يَهْدِ لَهُمْ كَمْ أَهْلَكْنَا قَبْلَهُم مِّنَ ٱلْقُرُونِ يَمْشُونَ فِى مَسَـٰكِنِهِمْ‌ۗ إِنَّ فِى ذَٲلِكَ لَأَيَـٰتٍ لِّأُوْلِى ٱلنُّهَىٰ ١٢٨ Is it not yet clear to them how many peoples We destroyed before them, whose ruins they still pass by? Surely in this are signs for people of sound judgment.
