Mishkat al-Masabih 5 Funerals كتاب الجنائز 141

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

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.
