Ruqyahٱللَّهُ لَآ إِلَـٰهَ إِلَّا هُوَ ٱلْحَىُّ ٱلْقَيُّومُ لَا تَأْخُذُهُ سِنَةٌ وَلَا نَوْمٌ لَّهُ مَا فِى ٱلسَّمَـٰوَٰتِ وَمَا فِى ٱلْأَرْضِ مَن ذَا ٱلَّذِى يَشْفَعُ عِندَهُ إِلَّا بِإِذْنِهِ يَعْلَمُ مَا بَيْنَ أَيْدِيهِمْ وَمَا خَلْفَهُمْ وَلَا يُحِيطُونَ بِشَىْءٍ مِّنْ عِلْمِهِ إِلَّا بِمَا شَآءَ وَسِعَ كُرْسِيُّهُ ٱلسَّمَـٰوَٰتِ وَٱلْأَرْضَ وَلَا يَؤُودُهُ حِفْظُهُمَا وَهُوَ ٱلْعَلِىُّ ٱلْعَظِيمُMeaningAllah — there is no god but He, the Ever-Living, the Sustainer of all. Neither drowsiness nor sleep overtakes Him. To Him belongs whatever is in the heavens and whatever is on the earth. Who can intercede with Him except by His permission? He knows what lies before them and what is behind them, and they encompass nothing of His knowledge except what He wills. His Throne extends over the heavens and the earth, and their preservation does not weary Him. He is the Most High, the Magnificent.
