“ʿAbdullah ibn ʿAwn wouldn’t get angry. If someone did happen to anger him he would say, ‘May Allaah bless you. (Bārakallāhu fīk).’”
Ḥilyatul-ʾAwliyā, vol. 3, p. 39.

Shaikh ʿAbdur-Razzāq al-Badr said, “Would that we would take heed of this and compare it to what we do and say when we get angry. He used to say this great duʿā to someone who made him angry, so what would he say when happy and relaxed? It is true strength and firmness that he contained himself like this when angry.”
