When Allah pardons those who say His name just once with love, will He not surely pardon those lovers who remember Him night and day? Will He deprive those lovers of His Grace, His Paradise and His beauty? Far is it from Him!
Therefore, we are told, if a person flings another's fault in his face, be it in public or in private, the earth itself appeals to Allah to let it deal with the one who exposes the other's fault. "My Lord," says the earth, "You are the Lord of All Worlds, yet You cover up the sins of Your servants, rather than flinging them in their faces. This man, himself a sinner, has disgraced a servant of Yours by exposing his offence. Pray permit me to swallow up this fellow, as I swallowed Qarun."
If a person sees another's sin, yet hides the fault he has seen and does not divulge it to others, Allah will cover up seventy of that person's sins and faults.
