Taha 20:128

Afalam yahdi lahum kam ahlaknaqablahum mina alqurooni yamshoona fee masakinihim inna feethalika laayatin li-olee annuha

Then, has it not become clear to them how many generations We destroyed before them as they walk among their dwellings? Indeed in that are signs for those of intelligence.

Did it give them no guidance (to realize) how many generations We have destroyed prior to them in whose dwellings they (often) walk around? Surely, in this there are signs for the men of reason.
