ahmad-zuhd:1632ʿAbdullāh from my father > Hishām > Ibn al-Mubārak > al-Ḥasan

[Machine] "Many a glance has ignited desire in the heart of its beholder, and many a desire has bestowed upon its owner long-lasting sadness."  

الزهد لأحمد:١٦٣٢حَدَّثَنَا عَبْدُ اللَّهِ حَدَّثَنَا أَبِي حَدَّثَنَا هِشَامٌ حَدَّثَنَا ابْنُ الْمُبَارَكِ عَنِ الْحَسَنِ قَالَ

«رُبَّ نَظْرَةٍ أَوْقَعَتْ فِي قَلْبِ صَاحِبِهَا شَهْوَةً وَرُبَّ شَهْوَةٍ أَوْرَثَتْ صَاحِبَهَا حُزْنًا طَوِيلًا»
