'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 صلى الله عليه وسلم  يقول‏:‏ “ إن المؤمن ليدرك بحسن خلقه درجة الصائم القائم” ‏(‏‏(‏رواه أبو داود‏)‏‏)‏‏.‏
