It was narrated from Simak bin Harb that 'Alqamah bin Wa'il told him that his father said:

"I was sitting with the Messenger of Allah when a man came leading another" (and he narrated) a similar report.

أَخْبَرَنَا زَكَرِيَّا بْنُ يَحْيَى، قَالَ حَدَّثَنَا عُبَيْدُ اللَّهِ بْنُ مُعَاذٍ، قَالَ حَدَّثَنَا أَبِي قَالَ، حَدَّثَنَا أَبُو يُونُسَ، عَنْ سِمَاكِ بْنِ حَرْبٍ، أَنَّ عَلْقَمَةَ بْنَ وَائِلٍ، حَدَّثَهُ أَنَّ أَبَاهُ حَدَّثَهُ قَالَ إِنِّي لَقَاعِدٌ مَعَ رَسُولِ اللَّهِ صلى الله عليه وسلم إِذْ جَاءَ رَجُلٌ يَقُودُ آخَرَ نَحْوَهُ ‏.‏
