ahmad-zuhd:1650ʿAbdullāh > al-Ḥakam b. Mūsá > Ḍamrah > Ibn Shawdhab > Ājtamaʿ al-Ḥasan And Muʿāwyah b. Qurrah Waʾashbāhuhumā Watadhākarūā Ay al-Aʿmāl Afḍal > Muʿāwiyah Fājtamaʿt > Khilāfihim

[Machine] Al-Hasan is more superior than the night vigil for performing a deed after striving in the cause of Allah, so Muawiyah said to him "the piousness", and Al-Hasan became angry and then said, "Indeed, it is not as such except in piety."  

الزهد لأحمد:١٦٥٠حَدَّثَنَا عَبْدُ اللَّهِ حَدَّثَنَا الْحَكَمُ بْنُ مُوسَى حَدَّثَنَا ضَمْرَةُ عَنِ ابْنِ شَوْذَبٍ قَالَ اجْتَمَعَ الْحَسَنُ وَمُعَاوِيَةُ بْنُ قُرَّةَ وَأَشْبَاهُهُمَا وَتَذَاكَرُوا أَيُّ الْأَعْمَالِ أَفْضَلُ؟ قَالَ مُعَاوِيَةُ فَاجْتَمَعْتُ عَلَى خِلَافِهِمْ فَقَالَ

الْحَسَنُ مَا عُمِلَ عَمَلٌ بَعْدَ الْجِهَادِ فِي سَبِيلِ اللَّهِ أَفْضَلُ مِنْ نَاشِئَةِ اللَّيْلِ فَقَالَ مُعَاوِيَةُ الْوَرَعُ فَغَضِبَ الْحَسَنُ ثُمَّ قَالَ «إِنَّهُ لَا يَكُونُ ذَلِكَ إِلَّا فِي الْوَرَعِ»
