0Book 3
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 .
Qatida reported:
I heard Anas as saying that the Companion of the Messenger of Allah (ﷺ) dozed off and then offered prayer and did not perform ablution. He (the narrator) said: I asked him if he had actually heard it from Anas. He said: By Allah. yes.
