محمد بن أبي عمير عن فضالة عن جميل قال: سألت أبا عبد الله عليه السلام عن قول الله تبارك وتعالى: فلا تزكوا أنفسكم هو اعلم بمن اتقى فقال: هو قول الانسان: صليت البارحة وصمت أمس ونحو هذا ثم قال عليه السلام: ان قوما كانوا يصبحون فيقولون: صلينا البارحة وصمنا أمس فقال علي عليه السلام لكني أنام الليل والنهار ولو أجد بينهما شيئا لنمته
9.Muḥammad ibn Abī ʿUmayr narrated from Faḍālah ibn Jamīl who said, “I asked Abā ʿAbdillāh  about the verse wherein Allah, the Blessed and Exalted, says: Do not assert your own virtue. He knows best who is truly virtuous (Q53:32). So he said, ‘It is when a person says: I prayed last night, and I fasted yesterday, and other statements such as these.’ Then he  said, ‘There were some people who would say in the mornings, “We prayed last night and we fasted yesterday,” so ʿAlī  said, “But as for me, I sleep at night and in the day, and were I to find between them any other time, I would have slept in it as well.”’” [1]
