Arabic hadith text
حَدَّثَنَا عَبْدُ اللَّهِ بْنُ مَسْلَمَةَ، عَنْ مَالِكٍ، عَنِ ابْنِ شِهَابٍ، عَنْ عُبَيْدِ اللَّهِ بْنِ عَبْدِ اللَّهِ بْنِ عُتْبَةَ، عَنِ ابْنِ عَبَّاسٍ ـ رضى الله عنهما ـ أَنَّهُ قَالَأَقْبَلْتُ رَاكِبًا عَلَى حِمَارٍ أَتَانٍ وَأَنَا يَوْمَئِذٍ قَدْ نَاهَزْتُ الاِحْتِلاَمَ وَرَسُولُ اللَّهِ صلى الله عليه وسلم يُصَلِّي 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 and I, then, had just attained the age of puberty. Allah's Messenger (ﷺ) was leading the people in prayer at Mina facing no wall. I passed in front of the row and let loose the sheass for grazing and joined the row and no one objected to my deed.
