مسلم:٢٥٥b – حَدَّثَنَا إِسْحَاقُ بْنُ إِبْرَاهِيمَ أَخْبَرَنَا جَرِيرٌ عَنْ مَنْصُورٍ ح وَحَدَّثَنَا ابْنُ نُمَيْرٍ حَدَّثَنَا أَبِي وَأَبُو مُعَاوِيَةَ عَنِ الأَعْمَشِ كِلاَهُمَا عَنْ أَبِي وَائِلٍ عَنْ حُذَيْفَةَ قَالَ

كَانَ رَسُولُ اللَّهِ ﷺ إِذَا قَامَ مِنَ اللَّيْلِ بِمِثْلِهِ وَلَمْ يَقُولُوا لِيَتَهَجَّدَ
