ahmad-zuhd:1462ʿAbdullāh from my father > Wakīʿ > ʿAbd al-Wāḥid b. Zayd > al-Ḥasan

[Machine] I have encountered people whose desire for food would increase as they aged, even if they were 70 years old. And I have also encountered people who, even at the age of 70, would not use a pillow to sleep on. One of them would eat a morsel of food as if it were a stone in his stomach.  

الزهد لأحمد:١٤٦٢حَدَّثَنَا عَبْدُ اللَّهِ حَدَّثَنَا أَبِي حَدَّثَنَا وَكِيعٌ حَدَّثَنَا عَبْدُ الْوَاحِدِ بْنُ زَيْدٍ عَنِ الْحَسَنِ قَالَ

لَقَدْ أَدْرَكْتُ أَقْوَامًا إِنْ كَانَ الرَّجُلُ مِنْهُمْ لَيَأْتِي عَلَيْهِ سَبْعُونَ سَنَةً مَا اشْتَهَى عَلَى أَهْلِهِ شَهْوَةَ طَعَامٍ وَلَقَدْ أَدْرَكْتُ أَقْوَامًا يَأْتِي عَلَى أَحَدِهِمْ سَبْعُونَ سَنَةً مَا تَوَسَّدَ وِسَادَةً وَإِنْ كَانَ أَحَدُهُمْ لَيَأْكُلُ الْأَكْلَةَ يُرِيدُ أَنَّهَا حَجَرٌ فِي بَطْنِهِ
