This is because, if an angry person remains standing while angry, he will stay close to the one who angered him and be poised to retaliate against him; he may strike him, slap him, or assault him. If he sits down, he moves farther away from him, and if he lies down, he is farther away still.

This indicates that an angry person should strive to control himself in both word and deed while angry, refraining from either until he has calmed down and regained his composure, so that his words are true and his actions just, free of error and excess.

Allah alone is asked to guide us and you to sound speech and righteous deeds, and to guide us all to the straight path.
