Arabic hadith text
حَدَّثَنَا الْحَسَنُ بْنُ عَلِيٍّ الْحُلْوَانِيُّ، وَعَبْدُ بْنُ حُمَيْدٍ، قَالاَ حَدَّثَنَا يَعْقُوبُ، - وَهُوَ ابْنُ إِبْرَاهِيمَ بْنِ سَعْدٍ - حَدَّثَنَا أَبِي، عَنْ صَالِحٍ، عَنِ ابْنِ شِهَابٍ، قَالَ حَدَّثَنِي عَامِرُ بْنُ سَعْدٍ، عَنْ أَبِيهِ، سَعْدٍ أَنَّهُ قَالَ أَعْطَى رَسُولُ اللَّهِ صلى الله عليه وسلم رَهْطًا وَأَنَا جَالِسٌ فِيهِمْ . بِمِثْلِ حَدِيثِ ابْنِ أَخِي ابْنِ شِهَابٍ عَنْ عَمِّهِ . وَزَادَ فَقُمْتُ إِلَى رَسُولِ اللَّهِ صلى الله عليه وسلم فَسَارَرْتُهُ فَقُلْتُ مَا لَكَ عَنْ فُلاَنٍ .
