Verse 10

أَفَلَمْ يَسِيرُوا۟ فِى ٱلْأَرْضِ فَيَنظُرُوا۟ كَيْفَ كَانَ عَـٰقِبَةُ ٱلَّذِينَ مِن قَبْلِهِمْ دَمَّرَ ٱللَّهُ عَلَيْهِمْ وَلِلْكَـٰفِرِينَ أَمْثَـٰلُهَا

Do they not travel throughout the land and see the consequences for those before them? God destroyed them and awaiting the unfaithful is a similar fate.
