The Book of Asceticism · Hadith 43 (#Ḥadīth #17)

الحسن بن محبوب عن أبي حمزة الثمالي قال: سمعت علي بن الحسين عليهما السلام يقول: من عمل بما فرض الله عليه فهو من خير الناس ومن اجتنبت ما حرم الله عليه فهو من أعبد الناس ومن قنع بما قسم الله له فهو من أغنى الناس.

17.Al-Ḥasan ibn Maḥbūb narrated from Abū Ḥamzah al-Thumālī who said, “ʿAlī ibn al-Ḥusayn said, ‘One who acts upon what Allah has made obligatory on him, he is among the best of people; and whoever eschews what Allah has forbidden him, he is among the most devoted of people; and whoever is content with what Allah has allotted for him, he is among the richest of people.’”
