The Holy Quran 30:23 — Surah Ar-Rum
Arabic text
وَمِنْ ءَايَـٰتِهِۦ مَنَامُكُم بِٱلَّيْلِ وَٱلنَّهَارِ وَٱبْتِغَآؤُكُم مِّن فَضْلِهِۦٓ ۚ إِنَّ فِى ذَٰلِكَ لَـَٔايَـٰتٍ لِّقَوْمٍ يَسْمَعُونَ
Translation
Also among His Aayaat is your sleep by night and by day (when you are oblivious of everything and wake up refreshed), and your seeking from His bounty (earning your livelihood). There are certainly Aayaat in this for those who listen (with the intention of taking heed).
Tafsir (excerpt) — Tafsir Usmani
