The Messenger of God, may God’s prayers and peace be upon him, said, “May God have mercy on a servant who spoke and was deafened or remained silent and then said hello. The tongue has power over anything for a human being. Indeed, the speech of a servant is entirely upon him except the remembrance of God, or enjoining what is right, or forbidding what is wrong, or reconciliation between believers,” so he said. Muadh ibn Jabal, O Messenger of God, shall we be held accountable for what we speak? He said: Is there anything that topples people on their noses into Hell other than the jests of their tongues? So whoever wants safety, let him preserve what his tongue has said, guard what his heart contains, do good deeds, and let his hopes be short.
