Verily everyone has faults, so do not expose that which is hidden from you, for indeed Allah, the Glorified, has hidden them out of clemency; and hide the faults [of others] as much as possible, [and in return] Allah, the Glorified, will hide that which you would like to remain hidden
The most honourable quality of the noble one is his feigning inattention [and ignorance] about that which he is aware [regarding the negative traits of others]
المصدر : غرر الحكم ودرر الكلم
تَأَمُّلُ الْعَيْبِ عَيْبٌ
Scrutinizing the faults of others is a fault [in itself]
المصدر : غرر الحكم ودرر الكلم
تَغَافَلْ يُحْمَدْ [يخمد] أَمْرُكَ
Feign heedlessness [about the mistakes of others] and your affair will be praised
