Sahih al-Bukhari 6048

'Adi ibn Thabit related that he heard Sulayman ibn Surad, one of the Companions of the Prophet, may Allah bless him and grant him peace, say, "Two men insulted one another in the presence of the Prophet, may Allah bless him and grant him peace, and one of them began angry. He became so angry that his face puffed out and changed. The Prophet, may Allah bless him and grant him peace, said, 'I know a word which, if he says it, it will remove what he feels.' The man went to him and told him what the Prophet, may Allah bless him and grant him peace, had said. he said, 'Seek refuge from Shaytan.' He said, 'Do you think that there is something which is wrong with me? Do you think that I am mad? Go away!'"
