Arabic hadith text
وَحَدَّثَنِي زُهَيْرُ بْنُ حَرْبٍ، حَدَّثَنَا يَعْقُوبُ بْنُ إِبْرَاهِيمَ، حَدَّثَنَا ابْنُ أَخِي ابْنِ شِهَابٍ،
ح وَحَدَّثَنَا حَسَنٌ الْحُلْوَانِيُّ، حَدَّثَنَا يَعْقُوبُ بْنُ إِبْرَاهِيمَ، حَدَّثَنَا أَبِي، عَنْ صَالِحٍ، ح وَحَدَّثَنَا
عَبْدُ بْنُ حُمَيْدٍ، أَخْبَرَنَا عَبْدُ الرَّزَّاقِ، أَخْبَرَنَا مَعْمَرٌ، كُلُّهُمْ عَنِ الزُّهْرِيِّ، بِهَذَا الإِسْنَادِ مِثْلَهُ
