Hadith Section/Book: Sahih Bukhari Sahih Bukhari Book 73. Good Manners and Form (Al-Adab)
Narated By Sulaiman bin Surad : A man from the companions of the Prophet said, "Two men abused each other in front of the Prophet and one of them became angry and his anger became so intense that his face became swollen and changed. The Prophet said, "I know a word the saying of which will cause him to relax if he does say it." Then a man went to him and informed him of the statement of the Prophet and said, "Seek refuge with Allah from Satan." On that, angry man said, 'Do you find anything wrong with me? Am I insane? Go away!"
