حَدَّثَنَا إِبْرَاهِيمُ بْنُ الْمُنْذِرِ، قَالَ: حَدَّثَنَا زَيْدُ بْنُ حُبَابٍ قَالَ: حَدَّثَنِي عُمَرُ بْنُ عُثْمَانَ بْنِ عَبْدِ الرَّحْمَنِ بْنِ سَعِيدٍ الْمَخْزُومِيُّ، حَدَّثَنِي جَدِّي، عَنْ أَبِيهِ، وَكَانَ اسْمُهُ الصَّرْمَ
فَسَمَّاهُ النَّبِيُّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ سَعِيدًا، قَالَ: رَأَيْتُ عُثْمَانَ رَضِيَ اللَّهُ عَنْهُ مُتَّكِئًا فِي الْمَسْجِدِ
