حَدَّثَنَا مُحَمَّدُ بْنُ عَبْدِ الْأَعْلَى التَّيْمِيُّ ، حَدَّثَنَا الْمُعْتَمِرُ ، عَنْ أَبِيهِ ، حَدَّثَنَا أَبُو السَّلِيلِ ، عَنْ زَهْدَمٍ يُحَدِّثُهُ ، عَنْ أَبِي مُوسَى ، قَالَ : كُنَّا مُشَاةً ، فَأَتَيْنَا نَبِيَّ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ نَسْتَحْمِلُهُ بِنَحْوِ حَدِيثِ جَرِيرٍ .
Abu Musa reported: We walked on foot and came to Allah's Apostle (ﷺ) (may peace he upon him) asking him to provide us with mounts. The rest of the hadith is the same.
