Preservation of Evidence

ذَٰلِكَ مِنْ أَنۢبَآءِ ٱلْقُرَىٰ نَقُصُّهُۥ عَلَيْكَ ۖ مِنْهَا قَآئِمٌ وَحَصِيدٌ

That is from the news of the cities, which We relate to you; of them, some are [still] standing and some are [as] a harvest [mowed down].

وَلَقَد تَّرَكْنَـٰهَآ ءَايَةً فَهَلْ مِن مُّدَّكِرٍ

And We left it as a sign, so is there any who will remember?
