15:85 We created not the heavens, the earth, and all between them, but for just ends. And the Hour is surely coming (when this will be manifest). So overlook (any human faults) with gracious forgiveness.
The Prophet(SAW) said “The servant who conceals the faults of others in the world, Allah would conceal his faults on the Day of Resurrection.” (Bukhari, Muslim)
The Prophet(SAW) said “O! Those who accepted Imaan with their tongues and the Imaan has not reached their hearts, do not backbite fellow Muslims and do not search for their faults for certainly who exposes the faults of others, Allah will expose his faults and disgrace him in his own home” (Bayhaqi 407/2)
The Prophet (SAW) also said “Let not a believing man hate a believing woman, if he dislikes one quality in her then he will be pleased with another.”
