It was narrated that Abu Musa said:
"The Messenger of Allah stood up among us and said five things. He said: 'Allah does not sleep, and it is not befitting that He should sleep. He lowers the Scales and raises them. The deed done during the day is taken up to Him before the deed done during the night, and the deed done during the night before the deed done during the day. His Veil is Light, and if He were to remove it, the glory of his Face would burn everything of His creation, as far as His gaze reaches.'"
حَدَّثَنَا عَلِيُّ بْنُ مُحَمَّدٍ، حَدَّثَنَا أَبُو مُعَاوِيَةَ، عَنِ الأَعْمَشِ، عَنْ عَمْرِو بْنِ مُرَّةَ، عَنْ أَبِي عُبَيْدَةَ، عَنْ أَبِي مُوسَى، قَالَ قَامَ فِينَا رَسُولُ اللَّهِ ـ صلى الله عليه وسلم ـ بِخَمْسِ كَلِمَاتٍ فَقَالَ ‏ "‏ إِنَّ اللَّهَ لاَ يَنَامُ وَلاَ يَنْبَغِي لَهُ أَنْ يَنَامَ يَخْفِضُ الْقِسْطَ وَيَرْفَعُهُ يُرْفَعُ إِلَيْهِ عَمَلُ اللَّيْلِ قَبْلَ عَمَلِ النَّهَارِ وَعَمَلُ النَّهَارِ قَبْلَ عَمَلِ اللَّيْلِ حِجَابُهُ النُّورُ لَوْ كَشَفَهُ لأَحْرَقَتْ سُبُحَاتُ وَجْهِهِ مَا انْتَهَى إِلَيْهِ بَصَرُهُ مِنْ خَلْقِهِ ‏"‏ ‏.‏
