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. (Using translation from Abū Dāʾūd 2572)   

سَمِعْتُ أَبِي بُرَيْدَةَ يَقُولُ بَيْنَمَا رَسُولُ اللهِ ﷺ يَمْشِي إِذْ جَاءَهُ رَجُلٌ مَعَهُ حِمَارٌ فَقَالَ يَا رَسُولَ اللهِ ارْكَبْ وَأَتَأَخَّرُ فَقَالَ رَسُولُ اللهِ ﷺ لَا أَنْتَ أَحَقُّ بِصَدْرِ دَابَّتِكَ مِنِّي تَرَى أَنْ تَجْعَلَهُ لِي؟ قَالَ فَإِنِّي قَدْ جَعَلْتُهُ لَكَ أَرْسَلَهُ غَيْرُهُ عَنْ عَبْدِ اللهِ  

[Machine] Muadh ibn Jabal came to the Prophet ﷺ with a mount, intending to ride it. The Messenger of Allah ﷺ said, "The owner of the mount has more right to its back." Muadh said, "It is for you, O Messenger of Allah." So the Prophet ﷺ mounted the mount and Muadh joined him.  

أَنَّ مُعَاذَ بْنَ جَبَلٍ أَتَى النَّبِيَّ ﷺ بِدَابَّةٍ؛ لِيَرْكَبَهَا فَقَالَ رَسُولُ اللهِ ﷺ رَبُّ الدَّابَّةِ أَحَقُّ بِصَدْرِهَا قَالَ مُعَاذٌ هِيَ لَكَ يَا رَسُولَ اللهِ قَالَ فَرَكِبَ النَّبِيُّ ﷺ وَأَرْدَفَ مُعَاذًا
