when feeling ANGRY

DU'A to recite when feeling ANGRY

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

(Sahih Bukhari 8.136)
