Hadith 5082
وَعَنْ عَائِشَةَ رَضِيَ اللَّهُ عَنْهَا قَالَتْ: سَمِعْتُ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ يَقُولُ: «إِنَّ الْمُؤْمِنَ لَيُدْرِكُ بِحُسْنِ خُلُقِهِ دَرَجَةَ قَائِمِ اللَّيْل وصائم النَّهَار» . رَوَاهُ أَبُو دَاوُد
Aisha (may Allah be pleased with her) narrates: I heard the Messenger of Allah (peace and blessings be upon him) say: "Indeed, a believer, because of his good character, attains the rank of one who fasts and stands (in prayer) at night." Hasan, narrated by Abu Dawood.
