﴿ ٱللَّهُ لَآ إِلَٰهَ إِلَّا هُوَ ٱلْحَىُّ ٱلْقَيُّومُ ۚ لَا تَأْخُذُهُۥ سِنَةٌۭ وَلَا نَوْمٌۭ ۚ لَّهُۥ مَا فِى ٱلسَّمَٰوَٰتِ وَمَا فِى ٱلْأَرْضِ ۗ مَن ذَا ٱلَّذِى يَشْفَعُ عِندَهُۥٓ إِلَّا بِإِذْنِهِۦ ۚ يَعْلَمُ مَا بَيْنَ أَيْدِيهِمْ وَمَا خَلْفَهُمْ ۖ وَلَا يُحِيطُونَ بِشَىْءٍۢ مِّنْ عِلْمِهِۦٓ إِلَّا بِمَا شَآءَ ۚ وَسِعَ كُرْسِيُّهُ ٱلسَّمَٰوَٰتِ وَٱلْأَرْضَ ۖ وَلَا يَـُٔودُهُۥ حِفْظُهُمَا ۚ وَهُوَ ٱلْعَلِىُّ ٱلْعَظِيمُ ﴾

“GOD - there is no deity save Him, the Ever-Living, the Self-Subsistent Fount of All Being. Neither slumber overtakes Him, nor sleep. His is all that is in the heavens and all that is on earth. Who is there that could intercede with Him, unless it be by His leave? He knows all that lies open before men and all that is hidden from them, whereas they cannot attain to aught of His knowledge save that which He wills [them to attain]. His eternal power overspreads the heavens and the earth, and their upholding wearies Him not. And he alone is truly exalted, tremendous.”

God, There is no god except Him, the Living, the Eternal Sustainer�He replied:This is the mightiest (aʿẓam) verse in God�s Book, Exalted is He. Within it is God�s Greatest Name, and it is written across the sky in green light in one line from East to West. This is how I saw it written on the Night of Great Merit (Laylat al-Qadr) in ʿAbbādān: There is no god except Him, the Living, the Eternal Sustainer.The Living, the Eternal Sustainer is the One who oversees everything pertaining to His creatures: their life spans, their actions, and their provision. He is the One who requites goodness (iḥsān) with goodness, and misdeeds with forgiveness (ghufrān), but He requites hypocrisy, disbelief and innovation with punishment. Whoever pronounces the saying: �There is no god except God� has made a pact with God, so it is unlawful for him, after making a pact with God, to disobey Him in any of His commandments or prohibitions, in secret or public, or to support His enemy, or to show enmity towards a friend of His.�No slumber can seize Him, nor sleep� Slumber (sina) here means sleepiness.He [Sahl] also said:Slumber is when the heart (qalb) is mingled with sleep.
