Surah Al Ankabut Tafseer

وَلَقَد تَّرَكْنَا مِنْهَا ايَةً بَيِّنَةً

And indeed We have left thereof an evident Ayah i.e., a clear sign,

..

لِّقَوْمٍ يَعْقِلُونَ

for a folk who understand.

This is like the Ayah,

وَإِنَّكُمْ لَّتَمُرُّونَ عَلَيْهِمْ مُّصْبِحِينَ

وَبِالَّيْلِ أَفَلَ تَعْقِلُونَ

Verily, you pass by them in the morning and at night; will you not then reflect. (37:137-138
