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.

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

(Using translation from Abū Dāʾūd 2572)

سَمِعْتُ أَبِي يَقُولُ بَيْنَا رَسُولُ اللهِ ﷺ يَمْشِي إِذْ جَاءَ رَجُلٌ مَعَهُ حِمَارٌ فَقَالَ يَا رَسُولَ اللهِ ارْكَبْ فَتَأَخَّرَ الرَّجُلُ فَقَالَرَسُولُ اللهِ ﷺ لَا أَنْتَ أَحَقُّ بِصَدْرِ دَابَّتِكَ مِنِّي إِلَّا أَنْ تَجْعَلَهُ لِي قَالَ فَإِنِّي قَدْ جَعَلْتُهُ لَكَ قَالَ فَرَكِبَ

"إِنَّ صَاحِبَ الدَّابَّةِ أَحَقُّ بِصَدْرِ دَابَّتِهِ إِلَّا أنْ تَجْعَلَهُ لى".
