باب نَدْبِ مَنْ حَلَفَ يَمِينًا فَرَأَى غَيْرَهَا خَيْرًا مِنْهَا أَنْ يَأْتِيَ الَّذِي هُوَ خَيْرٌ وَيُكَفِّرَ عَنْ يَمِينِهِ

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