Surah Al-'Ankabut — Ayah 35 (29:35)
وَلَقَد تَّرَكۡنَا مِنۡهَآ ءَايَةَۢ بَيِّنَةٗ لِّقَوۡمٖ يَعۡقِلُونَ ٣٥
English translation (Saheeh International)
And We have certainly left of it a sign as clear evidence for a people who use reason.
Brief commentary
I left some of this town that I destroyed as a clear sign for those who use their intellect for sound reasoning, because they are the ones who take a lesson from the signs.
