Sunan Ibn Majah 21
It was narrated from Abu Hurairah that :
The Prophet said "I do not want to hear of anyone of you who, upon hearing a Hadith narrated from me, says while reclining on his pillow: 'Recite Qur'an (to verify this Hadith).' (Here the Propher SAW said) Any excellent word that is said, it is I who have said it." [How can you reject what I have said?]
حَدَّثَنَا عَلِيُّ بْنُ الْمُنْذِرِ، حَدَّثَنَا مُحَمَّدُ بْنُ الْفُضَيْلِ، حَدَّثَنَا الْمَقْبُرِيُّ، عَنْ جَدِّهِ، عَنْ أَبِي هُرَيْرَةَ، عَنِ النَّبِيِّ ـ صلى الله عليه وسلم ـ أَنَّهُ قَالَ ‏
"‏ لاَ أَعْرِفَنَّ مَا يُحَدَّثُ أَحَدُكُمْ عَنِّي الْحَدِيثَ وَهُوَ مُتَّكِئٌ عَلَى أَرِيكَتِهِ فَيَقُولُ اقْرَأْ قُرْآنًا ‏.‏ مَا قِيلَ مِنْ قَوْلٍ حَسَنٍ فَأَنَا قُلْتُهُ ‏"‏ ‏.‏
