Avoiding anger for the sake of Allaah is a sign of the people of Paradise. Abud-Dardaa related that on one occasion he asked the Prophet (peace and blessings be upon him), “Messenger of Allaah, show me a deed which will put me in paradise.” Allaah’s messenger replied, “Don’t get angry and paradise will be yours.”Majma‘ az-Zawaa’id, vol. 8, p. 70
