Ibn 'Umar (May Allah be pleased with them) reported:
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."[At-Tirmidhi] (DE)
