A good word is charity.

This hadith expands charity beyond money and places generosity within reach of every tongue. A good word can steady someone who is ashamed, soften a conflict before it spreads, or remind a tired believer that Allah has not abandoned them. The tongue is small, but it can give relief or cause wounds people carry for years.

Calling a good word charity means it has weight with Allah. It is not filler. It is not merely being nice. When you choose encouragement over sarcasm, concealment over exposure, duʿāʾ over complaint, and truth over flattery, you are spending from the character Allah gave you. Many people are starving for a sentence that restores dignity. Do not underestimate the sadaqah you can give before the day ends.
