Changing evil by hand, tongue or heart

On the authority of Abū Saʿīd al-Khudrī, may Allah be pleased with him, who said: I heard the Messenger of Allah ﷺ say: Whoever of you sees an evil, let him change it with his hand; if he is not able, then with his tongue; and if he is not able, then with his heart, and that is the weakest of faith.
