Sahih Muslim 399bBook 4, Hadith 53
حَدَّثَنَا مُحَمَّدُ بْنُ الْمُثَنَّى، حَدَّثَنَا أَبُو دَاوُدَ، حَدَّثَنَا شُعْبَةُ، فِي هَذَا الإِسْنَادِ . وَزَادَ قَالَ شُعْبَةُ فَقُلْتُ لِقَتَادَةَ أَسَمِعْتَهُ مِنْ أَنَسٍ قَالَ نَعَمْ نَحْنُ سَأَلْنَاهُ عَنْهُ .
" I said to Qatada: Did you hear it from Anas? He replied in the affir- mative and added: We had inquired of him about it."
