Arabic hadith text
وَحَدَّثَنَا إِسْحَاقُ بْنُ إِبْرَاهِيمَ، وَعَبْدُ بْنُ حُمَيْدٍ، قَالاَ أَخْبَرَنَا عَبْدُ الرَّزَّاقِ، أَخْبَرَنَا مَعْمَرٌ، ح وَحَدَّثَنَا حَسَنٌ الْحُلْوَانِيُّ، وَعَبْدُ بْنُ حُمَيْدٍ، قَالاَ حَدَّثَنَا يَعْقُوبُ، - وَهُوَ ابْنُ إِبْرَاهِيمَ بْنِ سَعْدٍ - قَالَ حَدَّثَنِي أَبِي، عَنْ صَالِحٍ، كِلاَهُمَا عَنِ الزُّهْرِيِّ، بِهَذَا الإِسْنَادِ مِثْلَهُ غَيْرَ أَنَّ حَدِيثَ صَالِحٍ انْتَهَى عِنْدَ قَوْلِهِ فَأَنْزَلَ اللَّهُ عَزَّ وَجَلَّ فِيهِ . وَلَمْ يَذْكُرِ الآيَتَيْنِ . وَقَالَ فِي حَدِيثِهِ وَيَعُودَانِ فِي تِلْكَ الْمَقَالَةِ . وَفِي حَدِيثِ مَعْمَرٍ مَكَانَ هَذِهِ الْكَلِمَةِ فَلَمْ يَزَالاَ بِهِ
