I am a young Muslim and I want to let my beard grow, but my father is strongly opposed to this. Should I let my beard grow or obey my parents?
Shaving the beard is haraam, and it is not permissible to do it for a parent or leader or boss, because obedience is only a duty in matters that are good and righteous. The Prophet (peace and blessings of Allaah be upon him) said: “There is no obedience to any created being (person) if it involves disobedience to the Creator.”
