Hazrat Mu'adh bin Jabal narrates that the Noble Prophet (peace and blessings be upon him) said to him: "Shall I not inform you of the root of all these things?"

I said, "O Messenger of Allah (peace and blessings be upon him)! Will we be held accountable for whatever we utter with our tongues?" The Prophet (peace and blessings be upon him) said, "O Mu'adh! May your mother lose you. The thing that will throw people on their faces into Hell will be the harvests of their tongues."
