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.”
