I heard the Prophet (ﷺ) saying, "A person utters a word thoughtlessly (i.e., without thinking about its being good or not) and, as a result of this, he will fall down into the fire of Hell deeper than the distance between the east and the west."

[Al-Bukhari and Muslim].

The Prophet (ﷺ) said, "A man utters a word pleasing to Allah without considering it of any significance for which Allah exalts his ranks (in Jannah); another one speaks a word displeasing to Allah without considering it of any importance, and for this reason he will sink down into Hell."

[Al-Bukhari].

The Messenger of Allah (ﷺ) said, "A man speaks a good word without knowing its worth, Allah records for him His Good Pleasure till the day he will meet Him; and a man utters an evil word without realizing its importance, Allah records for him His displeasure till the day he will meet Him."

I asked: "O Messenger of Allah! Tell me, of something to which I may remain steadfast." He (ﷺ) said, "Say: My Rubb is Allah and then remain steadfast." Then I said: "O Messenger of Allah! What do you fear most about me?" He took hold of his own tongue and said: "This."

[At-Tirmidhi].

The Messenger of Allah (ﷺ) said, "Do not indulge in excessive talk except when remembering Allah. Excessive talking without the Remembrance of Allah hardens the heart; and those who are the farthest from Allah are those whose hearts are hard."
