Hadith 4:141
Jabir b. Samura said the Prophet was brought an unsaddled horse which he rode when he went away after the funeral of Ibn ad-Dahdah, and they went on foot around him. Muslim transmitted it.
وَعَنْ جَابِرِ بْنِ سَمُرَةَ قَالَ: أَتَى النَّبِيُّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ بِفَرَسٍ مَعْرُورٍ فَرَكِبَهُ حِينَ انْصَرَفَ مِنْ جَنَازَةِ ابْنِ الدَّحْدَاحِ وَنَحْنُ نمشي حوله. رَوَاهُ مُسلم
