It was narrated that Isma’il bin Abu Khalid said:“I saw Abu Kahil, and he was a Companions, and my brother narrated to me that he said: ‘I saw the Prophet (ﷺ) delivering the sermon atop his she-camel, and an Ethiopian was holding onto its reins.’”
حَدَّثَنَا مُحَمَّدُ بْنُ عَبْدِ اللَّهِ بْنِ نُمَيْرٍ، حَدَّثَنَا وَكِيعٌ، عَنْ إِسْمَاعِيلَ بْنِ أَبِي خَالِدٍ، قَالَ رَأَيْتُ أَبَا كَاهِلٍ وَكَانَتْ لَهُ صُحْبَةٌ فَحَدَّثَنِي أَخِي، عَنْهُ قَالَ رَأَيْتُ النَّبِيَّ ـ صلى الله عليه وسلم ـ يَخْطُبُ عَلَى نَاقَةٍ وَحَبَشِيٌّ آخِذٌ بِخِطَامِهَا .
