quran:29:35 –

And We have certainly left of it a sign as clear evidence for a people who use reason.  

And verily We have left of that a clear sign, a manifest one — namely, the remains of its ˹the town’s˺ ruins — for a people who understand, ˹a people who˺ reflect.
القرآن:٢٩:٣٥ –

وَلَقَدْ تَرَكْنَا مِنْهَا آيَةً بَيِّنَةً لِقَوْمٍ يَعْقِلُونَ  

{ولقد تركنا منها آية بينة} ظاهرة هي آثار خرابها {لقوم يعقلون} يتدبرون.
