وَحَدَّثَنِي إِسْحَاقُ بْنُ مَنْصُورٍ، حَدَّثَنَا النَّضْرُ بْنُ شُمَيْلٍ، أَخْبَرَنَا شُعْبَةُ، عَنِ الْحَكَمِ، قَالَ سَمِعْتُ ذَرًّا، عَنِ ابْنِ عَبْدِ الرَّحْمَنِ بْنِ أَبْزَى، قَالَ قَالَ الْحَكَمُ وَقَدْ سَمِعْتُهُ مِنِ ابْنِ عَبْدِ الرَّحْمَنِ بْنِ أَبْزَى، عَنْ أَبِيهِ، أَنَّ رَجُلاً، أَتَى عُمَرَ فَقَالَ إِنِّي أَجْنَبْتُ فَلَمْ أَجِدْ مَاءً . وَسَاقَ الْحَدِيثَ وَزَادَ فِيهِ قَالَ عَمَّارٌ يَا أَمِيرَ الْمُؤْمِنِينَ إِنْ شِئْتَ لِمَا جَعَلَ اللَّهُ عَلَىَّ مِنْ حَقِّكَ لاَ أُحَدِّثُ بِهِ أَحَدًا وَلَمْ يَذْكُرْ حَدَّثَنِي سَلَمَةُ عَنْ ذَرٍّ .
