'Aishah (May Allah be pleased with her) reported:
I heard Messenger of Allah ﷺ saying: "A believer will attain by his good behaviour the rank of one who prays during the night and observes fasting during the day."

[Abu Dawud].

وعن عائشة رضي الله عنها، قالت: سمعت رسول الله ﷺ يقول: “ إن المؤمن ليدرك بحسن خلقه درجة الصائم القائم” ((رواه أبو داود)).
