وَحَدَّثَنِي يَحْيَى بْنُ حَبِيبٍ الْحَارِثِيُّ، حَدَّثَنَا خَالِدٌ، - وَهُوَ ابْنُ الْحَارِثِ - حَدَّثَنَا شُعْبَةُ، عَنْ قَتَادَةَ، قَالَ سَمِعْتُ أَنَسًا، يَقُولُ كَانَ أَصْحَابُ رَسُولِ اللَّهِ صلى الله عليه وسلم يَنَامُونَ ثُمَّ يُصَلُّونَ وَلاَ يَتَوَضَّئُونَ قَالَ قُلْتُ سَمِعْتَهُ مِنْ أَنَسٍ قَالَ إِي وَاللَّهِ
