Hadith 15:259
Sahih (Al-Albani)
The tradition mentioned above has also been transmitted by Abu ‘Umrah through a different chain of narrators to the same effect. But this version has “Three Persons” and added “To the horseman three portions.”
حَدَّثَنَا مُسَدَّدٌ، حَدَّثَنَا أُمَيَّةُ بْنُ خَالِدٍ، حَدَّثَنَا الْمَسْعُودِيُّ، عَنْ رَجُلٍ، مِنْ آلِ أَبِي عَمْرَةَ عَنْ أَبِي عَمْرَةَ، بِمَعْنَاهُ إِلاَّ أَنَّهُ قَالَ ثَلاَثَةَ نَفَرٍ . زَادَ فَكَانَ لِلْفَارِسِ ثَلاَثَةُ أَسْهُمٍ
