Hadith of the Prophet SAW

• When you become angry, desist from speaking ill.
• Shall I not inform you of two things which require little effort, yet provide great reward? From among the deeds with which one meets Allah Ta’ala there are none such as these: silence and good character.
• A man has not swallowed a mouthful more pleasing to Allah Ta’ala than that of uncontrollable anger, or a mouthful of patience in a time of hardship.

Kalam of Imam Ali ibn Talib AS

• Some words can be more piercing than the blow of an arrow.
• Long-windedness is the flaw of speech.
