Abu Dawud Book 36, Hadith Number 4762.

Narated By Mu’adh ibn Jabal : Two men reviled each other in the presence of the Prophet (PBUH) and one of them became excessively angry so much so that I thought that his nose will break up on account of excess of anger. The Prophet (PBUH) said: I know a phrase which, if he repeated, he could get rid of this angry feeling. They asked: What is it, Apostle of Allah? He replied: He should say: I seek refuge in Thee from the accursed devil. Mu’adh then began to ask him to do so, but he refused and persisted in quarrelling, and began to enhance his anger.
