Shaikh Saaleh Al-Fawzaan (may Allaah preserve him) stated in It’haaf At-Tullaab Bi-Sharh Mandhoomah Al-Aadaab page 85: From the nuisances caused by the tongue: Excessive speech!
A person should not be a chatterbox-always talking without a benefit. This is excessive speech and a loss for him. He makes his tongue and the listeners tired with speech that is fruitless. He speaks in the gatherings and during every occasion without benefit. Therefore, a person should restrain his tongue from excess speech – unneeded speech. [Slightly paraphrased]
