Sahih Muslim , Book 4, Hadith 2110 (USC-MSA) ⓘ
It is reported on the authority of Jabir ibn Samura that an unsaddled horse was brought to the Prophet and he rode on it when he returned after having offered the funeral prayer of Ibn Dahdah and we walked on foot around him.
حَدَّثَنَا يَحْيَى بْنُ يَحْيَى، وَأَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ - وَاللَّفْظُ لِيَحْيَى - قَالَ أَبُو بَكْرٍ حَدَّثَنَا وَقَالَ، يَحْيَى أَخْبَرَنَا وَكِيعٌ، عَنْ مَالِكِ بْنِ مِغْوَلٍ، عَنْ سِمَاكِ بْنِ حَرْبٍ، عَنْ جَابِرِ بْنِ، سَمُرَةَ قَالَ أُتِيَ النَّبِيُّ صلى الله عليه وسلم بِفَرَسٍ مُعْرَوْرًى فَرَكِبَهُ حِينَ انْصَرَفَ مِنْ جَنَازَةِ ابْنِ الدَّحْدَاحِ وَنَحْنُ نَمْشِي حَوْلَهُ .
