ahmad-zuhd:1505ʿAbdullāh from my father > ʿAlī b. Jaʿfar > Sulaymān b. al-Mughīrah > Yūnus b. ʿUbayd

[Machine] I have never seen a longer sadness than Al-Hassan's, and he used to say, "We laugh, but perhaps Allah has seen our deeds and said, 'I will not accept anything from you.'"  

الزهد لأحمد:١٥٠٥حَدَّثَنَا عَبْدُ اللَّهِ حَدَّثَنَا أَبِي حَدَّثَنَا عَلِيُّ بْنُ جَعْفَرٍ حَدَّثَنَا سُلَيْمَانُ بْنُ الْمُغِيرَةِ عَنْ يُونُسَ بْنِ عُبَيْدٍ قَالَ

مَا رَأَيْتُ أَطْوَلَ حُزْنًا مِنَ الْحَسَنِ وَكَانَ يَقُولُ نَضْحَكُ وَلَعَلَّ اللَّهَ قَدْ اطَّلَعَ عَلَى أَعْمَالِنَا فَقَالَ لَا أَقْبَلُ مِنْكُمْ شَيْئًا
