Sunan Ibn Majah, Book 37, Hadith 4318 (In-Book) ⓘ

It was narrated that Anas bin Malik said: “The Messenger of Allah used to visit the sick, attend funerals, accept the invitations of slaves and ride donkeys. On the day (of the battle) of Quraizah and Nadir, he was riding a donkey. On the day of Khaibar he was riding a donkey that was bridled with palmfibers and beneath him was a packsaddle made of palmfibers.”

حَدَّثَنَا عَمْرُو بْنُ رَافِعٍ، حَدَّثَنَا جَرِيرٌ، عَنْ مُسْلِمٍ الأَعْوَرِ، عَنْ أَنَسِ بْنِ مَالِكٍ، قَالَ كَانَ رَسُولُ اللَّهِ ـ صلى الله عليه وسلم ـ يَعُودُ الْمَرِيضَ وَيُشَيِّعُ الْجِنَازَةَ وَيُجِيبُ دَعْوَةَ الْمَمْلُوكِ وَيَرْكَبُ الْحِمَارَ وَكَانَ يَوْمَ قُرَيْظَةَ وَالنَّضِيرِ عَلَى حِمَارٍ وَيَوْمَ خَيْبَرَ عَلَى حِمَارٍ مَخْطُومٍ بِرَسَنٍ مِنْ لِيفٍ وَتَحْتَهُ إِكَافٌ مِنْ لِيفٍ ‏"‏ ‏.‏
