Sunan of Abu Dawood Book 20, Hadith 3075

حَدَّثَنَا أَحْمَدُ بْنُ سَعِيدٍ الدَّارِمِيُّ، حَدَّثَنَا وَهْبٌ، عَنْ أَبِيهِ، عَنِ ابْنِ إِسْحَاقَ، بِإِسْنَادِهِ وَمَعْنَاهُ إِلاَّ أَنَّهُ قَالَ عِنْدَ قَوْلِهِ مَكَانَ الَّذِي حَدَّثَنِي هَذَا فَقَالَ رَجُلٌ مِنْ أَصْحَابِ النَّبِيِّ صلى الله عليه وسلم وَأَكْثَرُ ظَنِّي أَنَّهُ أَبُو سَعِيدٍ الْخُدْرِيُّ فَأَنَا رَأَيْتُ الرَّجُلَ يَضْرِبُ فِي أُصُولِ النَّخْلِ ‏.‏

The tradition mentioned above has also been transmitted by Ibn Ishaq through a different chain of narrators and to the same effect. Instead of the phrase "one who transmitted this tradition to me" this version has "A man from among the Companions of the Prophet (ﷺ) and probably he was Abu Sa'id Al Khudri. I saw the man striking at the roots of the palm trees."
