Bulugh al-Maram, Book 16, Hadith 1510 (In-Book) ⓘ
Anas (RAA) narrated that the Messenger of Allah 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. (1972). 2 - ضعيف جدا وله شواهد، ولكنها كلها ضعيفة -أيضا- كما قال الحافظ العراقي.
