Sulayman ibn Sard narrated that two men were trading insults in the presence of the Prophet (peace and blessings of Allah be upon them), until the face of one of them turned red. The Prophet (peace and blessings of Allah be upon him) said, “I know a word which, if he were to say it, what he is suffering from would go away: ‘A’udhu Billahi min al-Shaytan il-rajim (I seek refuge with Allah from the accursed shaytan).’” (al-Bukhari and Muslim)
