Narated By Sulaiman bin Sarad : Two men abused each other in front of the Prophet while we were sitting with him. One of the two abused his companion furiously and his face became red. The Prophet said, "I know a word (sentence) the saying of which will cause him to relax if this man says it. Only if he said, "I seek refuge with Allah from Satan, the outcast.' " So they said to that (furious) man, 'Don't you hear what the Prophet is saying?" He said, "I am not mad."
