Mishkat al-Masabih 91
Abu'Musa said :
God’s messenger stood up among us and made five statements, saying, “God does not sleep, as it is unfitting that He should do so; He lowers the scale and raises it up; the deeds done by night are taken up to Him before the day’s deeds are done; the deeds done by day before the night’s deeds are done; His veil is light, if He were to remove it His majesty would burn up all His creation which was reached by His glance.” 

Muslim transmitted it.
وَعَن أبي مُوسَى قَالَ قَامَ فِينَا رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ بِخَمْسِ كَلِمَاتٍ فَقَالَ: «إِنَّ اللَّهَ عز وَجل لَا يَنَامُ وَلَا يَنْبَغِي لَهُ أَنْ يَنَامَ يَخْفِضُ الْقِسْطَ وَيَرْفَعُهُ يُرْفَعُ إِلَيْهِ عَمَلُ اللَّيْلِ قَبْلَ عَمَلِ النَّهَارِ وَعَمَلُ النَّهَارِ قَبْلَ عَمَلِ اللَّيْل حجابه النُّور» . رَوَاهُ مُسلم
