It was narrated that Anas bin Malik said:
“The Messenger of Allah ﷺ 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 ﷺ 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 " .
