2:255 ٱللَّهُ لَآ إِلَٰهَ إِلَّا هُوَ ٱلْحَىُّ ٱلْقَيُّومُ لَا تَأْخُذُهُۥ سِنَةٌ وَلَا نَوْمٌ لَّهُۥ مَا فِى ٱلسَّمَٰوَٰتِ وَمَا فِى ٱلْأَرْضِ مَن ذَا ٱلَّذِى يَشْفَعُ عِندَهُۥٓ إِلَّا بِإِذْنِهِۦ يَعْلَمُ مَا بَيْنَ أَيْدِيهِمْ وَمَا خَلْفَهُمْ وَلَا يُحِيطُونَ بِشَىْءٍ مِّنْ عِلْمِهِۦٓ إِلَّا بِمَا شَآءَ وَسِعَ كُرْسِيُّهُ ٱلسَّمَٰوَٰتِ وَٱلْأَرْضَ وَلَا يَـُٔودُهُۥ حِفْظُهُمَا وَهُوَ ٱلْعَلِىُّ ٱلْعَظِيمُ
Allah is He besides Whom there is no god, the Everliving, the Self-subsisting by Whom all subsist; slumber does not overtake Him nor sleep; whatever is in the heavens and whatever is in the earth is His; who is he that can intercede with Him but by His permission? He knows what is before them and what is behind them, and they cannot comprehend anything out of His knowledge except what He pleases, His knowledge extends over the heavens and the earth, and the preservation of them both tires Him not, and He is the Most High, the Great.
And certainly We tried Sulaiman, and We put on his throne a (mere) body, so he turned (to Allah).
