أَوَلَمْ يَسِيرُوا۟ فِى ٱلْأَرْضِ فَيَنظُرُوا۟ كَيْفَ كَانَ عَٰقِبَةُ ٱلَّذِينَ مِن قَبْلِهِمْ ۚ كَانُوٓا۟ أَشَدَّ مِنْهُمْ قُوَّةًۭ وَأَثَارُوا۟ ٱلْأَرْضَ وَعَمَرُوهَآ أَكْثَرَ مِمَّا عَمَرُوهَا وَجَآءَتْهُمْ رُسُلُهُم بِٱلْبَيِّنَٰتِ ۖ فَمَا كَانَ ٱللَّهُ لِيَظْلِمَهُمْ وَلَٰكِن كَانُوٓا۟ أَنفُسَهُمْ يَظْلِمُونَ
Have they not travelled in the land and seen the nature of the consequence for those who were before them? They were stronger than these in power, and they dug the earth and built upon it more than these have built. Messengers of their own came unto them with clear proofs (of Allah's Sovereignty). Surely Allah wronged them not, but they did wrong themselves.
Surah Ar-Room(30:9)
