أَنَّهُ كَانَ يُحْيِي لَيْلَةَ ثَلَاثٍ وَعِشْرِينَ مِنْ شَهْرِ رَمَضَانَ وَلَيْلَةَ سَبْعٍ وَعِشْرِينَ وَلَا كَإِحْيَائِهِ لَيْلَةَ سَبْعَ عَشْرَةَ فَقِيلَ لَهُ كَيْفَ تَخُصُّ لَيْلَةَ سَبْعَ عَشْرَةَ؟ فَقَالَ «إِنَّ فِيهَا نَزَلَ الْقُرْآنُ وَفِي صَبِيحَتِهَا فُرِّقَ بَيْنَ الْحَقِّ وَالْبَاطِلِ وَكَانَ فِيهَا يُصْبِحُ مُبْهَجَ الْوَجْهِ»
