Arabic hadith text
حَدَّثَنَا عَبْدُ اللَّهِ بْنُ يُوسُفَ، قَالَ أَخْبَرَنَا مَالِكٌ، عَنِ ابْنِ شِهَابٍ، عَنْ عُبَيْدِ اللَّهِ بْنِ عَبْدِ اللَّهِ بْنِ عُتْبَةَ، عَنْ عَبْدِ اللَّهِ بْنِ عَبَّاسٍ، أَنَّهُ قَالَ أَقْبَلْتُ رَاكِبًا عَلَى حِمَارٍ أَتَانٍ، وَأَنَا يَوْمَئِذٍ قَدْ نَاهَزْتُ الاِحْتِلاَمَ، وَرَسُولُ اللَّهِ صلى الله عليه وسلميُصَلِّي بِالنَّاسِ بِمِنًى إِلَى غَيْرِ جِدَارٍ، فَمَرَرْتُ بَيْنَ يَدَىْ بَعْضِ الصَّفِّ، فَنَزَلْتُ وَأَرْسَلْتُ الأَتَانَ تَرْتَعُ، وَدَخَلْتُ فِي الصَّفِّ، فَلَمْ يُنْكِرْ ذَلِكَ عَلَىَّ أَحَدٌ‏.‏
Translation
Narrated Ibn `Abbas

Once I came riding a she-ass when I had just attained the age of puberty. Allah's Messenger (ﷺ) was offering the prayer at Mina with no wall in front of him and I passed in front of some of the row. There I dismounted and let my she-ass loose to graze and entered the row and nobody objected to me about it.
