Sayyiduna Sulaiman bin Surad (may Allah be pleased with him) narrates: Two men began to argue in the presence of the Prophet Muhammad (peace and blessings be upon him). We were sitting with the Prophet (peace and blessings be upon him) at that time. One of them, in a state of anger, started abusing his companion. That person's face turned red. The Prophet (peace and blessings be upon him) said: I know of a word, if he were to say it, the anger he is experiencing would go away. That word is: "A'udhu billahi min ash-shaytan ir-rajim" (I seek refuge with Allah from the accursed devil). The people said to that man: Did you not hear what the Prophet (peace and blessings be upon him) said? He replied: I am not mad. (Meaning, I have heard it.)
