حَدَّثَنِي يَحْيَى، عَنْ مَالِكٍ، عَنِ ابْنِ شِهَابٍ، عَنْ عُبَيْدِ اللَّهِ بْنِ عَبْدِ اللَّهِ بْنِ عُتْبَةَ بْنِ مَسْعُودٍ، عَنْ عَبْدِ اللَّهِ بْنِ عَبَّاسٍ، أَنَّهُ قَالَ أَقْبَلْتُ رَاكِبًا عَلَى أَتَانٍ - وَأَنَا يَوْمَئِذٍ قَدْ نَاهَزْتُ الاِحْتِلاَمَ - وَرَسُولُ اللَّهِ صلى الله عليه وسلم يُصَلِّي لِلنَّاسِ بِمِنًى فَمَرَرْتُ بَيْنَ يَدَىْ بَعْضِ الصَّفِّ فَنَزَلْتُ فَأَرْسَلْتُ الأَتَانَ تَرْتَعُ وَدَخَلْتُ فِي الصَّفِّ فَلَمْ يُنْكِرْ ذَلِكَ عَلَىَّ أَحَدٌ ‏.‏

Yahya related to me from Malik from Ibn Shihab from Ubaydullahibn Abdullah ibn Utba ibn Masud that Abdullah ibn Abbas said, "Iapproached, riding on a donkey, while the Messenger of Allah, mayAllah bless him and grant him peace, was leading the people in prayerat Mina, and I was, at that time, nearing puberty. I passed in frontof part of the row, dismounted, sent the donkey off to graze, and thenjoined the row, and no one rebuked me for doing so." Translation Not Available
