Imam Ali (AS) said to Qanbar when he wished to insult a man who had insulted him, 'Careful Qanbar! Leave your insulter to his disdain and you will please the Beneficent Lord, displease Satan and punish thereby your enemy, for by the One who split the grain and created the breeze, there is no stance better than clemency with which a believer can please his Lord, and nothing like silence to offend Satan, and an idiot is best punished by ignoring him.
