الزهد لأحمد:١٥١٥حَدَّثَنَا عَبْدُ اللَّهِ حَدَّثَنِي أَبِي حَدَّثَنَا عَفَّانُ حَدَّثَنَا مَهْدِيٌّ حَدَّثَنَا مُحَمَّدُ بْنُ عَبْدِ اللَّهِ بْنِ أَبِي يَعْقُوبَ عَنْ مَرْزُوقٍ الْعِجْلِيِّ قَالَ

قَالَ لِي أَبُو قَتَادَةَ الْعَدَوِيُّ الْزَمْ هَذَا الشَّيْخَ وَخُذْ عَنْهُ يَعْنِي الْحَسَنَ فَوَاللَّهِ مَا رَأَيْتُ رَجُلًا أَشْبَهَ أدَبًا بِعُمَرَ بْنِ الْخَطَّابِ مِنْهُ
