"The Messenger of Allah would visit the sick, attend the funerals, ride a donkey, accept the invitation of a slave, and on the Day of Banu Quraizah he was on a donkey muzzled with a cord of fibers and a pack-saddle made of fibers."  

كَانَ رَسُولُ اللَّهِ ﷺ يَعُودُ الْمَرِيضَ وَيَشْهَدُ الْجَنَازَةَ وَيَرْكَبُ الْحِمَارَ وَيُجِيبُ دَعْوَةَ الْعَبْدِ وَكَانَ يَوْمَ بَنِي قُرَيْظَةَ عَلَى حِمَارٍ مَخْطُومٍ بِحَبْلٍ مِنْ لِيفٍ عَلَيْهِ إِكَافُ لِيفٍ  

“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.” (Using translation from Ibn Mājah 4178)   

كَانَ رَسُولُ اللَّهِ ﷺ «يَعُودُ الْمَرِيضَ وَيَتْبَعُ الْجَنَائِزَ وَيُجِيبُ دَعْوَةَ الْمَمْلُوكِ وَيَرْكَبُ الْحِمَارَ وَلَقَدْ كَانَ يَوْمَ خَيْبَرَ وَيَوْمَ قُرَيْظَةَ عَلَى حِمَارٍ خِطَامُهُ حَبْلٌ مِنْ لِيفٍ وَتَحْتَهُ إِكَافٌ مِنْ لِيفٍ»
