حَدَّثَنَا حَمَّادُ بْنُ خَالِدٍ حَدَّثَنَا ابْنُ أَبِي ذِئْبٍ عَنْ شُعْبَةَ عَنِ ابْنِ عَبَّاسٍ قَالَ مَرَرْتُ أَنَا وَالْفَضْلُ عَلَى أَتَانٍ وَرَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ يُصَلِّي بِالنَّاسِ فِي فَضَاءٍ مِنْ الْأَرْضِ فَنَزَلْنَا وَدَخَلْنَا مَعَهُ فَمَا قَالَ لَنَا فِي ذَلِكَ شَيْئًا
مسند امام احمد بن حنبل · Hadith 3019
It was narrated that Ibn 'Abbas (RA) said: al-Fadl and I passed by on a donkey when the Messenger of Allah (PBUH) was leading the people in prayer on some open ground. We dismounted and joined him, and he did not say anything to us about that.
