➊ By concealing (pardah poshi) is meant to refrain from exposing or publicizing someone’s sin or fault.
➋ No human being is free from faults or mistakes; therefore, one should avoid disgracing others.
➌ In the Hereafter, concealing (pardah rakhna) means forgiveness of one’s sins.
➍ A good recompense for showing kindness to someone is received both in this world and in the Hereafter. The way a person treats another, Allah Ta’ala also treats him in the same manner.
