Anas (RAA) narrated that the Messenger of Allah (ﷺ) said:

“Blessed is he who is preoccupied with his defects rather than those of other people.” Related by Al-Bazzar with a good chain of narrators.

وَعَنْ أَنَسٍ ‏- رضى الله عنه ‏- قَالَ: قَالَ رَسُولُ اَللَّهِ ‏- صلى الله عليه وسلم ‏-{ طُوبَى لِمَنْ شَغَلَهُ عَيْبَهُ عَنْ عُيُوبِ اَلنَّاسِ } أَخْرَجَهُ اَلْبَزَّارُ بِإِسْنَادٍ حَسَنٍ.‏ [1]‏ .‏
