أحمد:٨٧٦٨ – حَدَّثَنَا عَلِيُّ بْنُ عَبْدِ اللهِ ابْنُ الْمَدِينِيِّ وَذَلِكَ قَبْلَ الْمِحْنَةِ قَالَ عَبْدُ اللهِ وَلَمْ يُحَدِّثْ أَبِي عَنْهُ بَعْدَ الْمِحْنَةِ بِشَيْءٍ قَالَ حَدَّثَنَا عَبْدُ الْوَهَّابِ بْنُ عَبْدِ الْمَجِيدِ يَعْنِي الثَّقَفِيَّ حَدَّثَنَا يُونُسُ عَنِ الْحَسَنِ عَنْ أَبِي هُرَيْرَةَ

أَنَّ النَّبِيَّ ﷺ قَالَ أَفْطَرَ الْحَاجِمُ وَالْمَحْجُومُ
