Nafi said :

I was sitting behind Ibn ‘Umar on the mount when he passed a shepherd who was blowing a pipe. He then mentioned the rest of the tradition in a similar manner. Abu Dawud said : Between Mut’im and Nafi the name of a narrator Sulaiman b. Musa has been inserted.

حَدَّثَنَا مَحْمُودُ بْنُ خَالِدٍ، حَدَّثَنَا أَبِي، حَدَّثَنَا مُطْعِمُ بْنُ الْمِقْدَامِ، قَالَ حَدَّثَنَا نَافِعٌ، قَالَ كُنْتُ رِدْفَ ابْنِ عُمَرَ إِذْ مَرَّ بِرَاعٍ يَزْمُرُ فَذَكَرَ نَحْوَهُ ‏.‏ قَالَ أَبُو دَاوُدَ أُدْخِلَ بَيْنَ مُطْعِمٍ وَنَافِعٍ سُلَيْمَانُ بْنُ مُوسَى ‏.‏
