Narrated Buraydah ibn al-Hasib:

While the Messenger of Allah ﷺ was walking a man who had an ass came to him and said: Messenger of Allah, ride; and the man moved to the back of the animal. The Messenger of Allah ﷺ said: No, you have more right to ride in front on your animal than me unless you grant that right to me. He said: I grant it to you. So he mounted.

حَدَّثَنَا أَحْمَدُ بْنُ مُحَمَّدِ بْنِ ثَابِتٍ الْمَرْوَزِيُّ، حَدَّثَنِي عَلِيُّ بْنُ حُسَيْنٍ، حَدَّثَنِي أَبِي، حَدَّثَنِي عَبْدُ اللَّهِ بْنُ بُرَيْدَةَ، قَالَ سَمِعْتُ أَبِي بُرَيْدَةَ، يَقُولُ بَيْنَمَا رَسُولُ اللَّهِ ﷺ يَمْشِي جَاءَ رَجُلٌ وَمَعَهُ حِمَارٌ فَقَالَ يَا رَسُولَ اللَّهِ ارْكَبْ . وَتَأَخَّرَ الرَّجُلُ . فَقَالَ رَسُولُ اللَّهِ ﷺ
" لاَ أَنْتَ أَحَقُّ بِصَدْرِ دَابَّتِكَ مِنِّي إِلاَّ أَنْ تَجْعَلَهُ لِي " . قَالَ فَإِنِّي قَدْ جَعَلْتُهُ لَكَ . فَرَكِبَ .
