Is Salaat valid behind a teacher who compels students to shave their beard?

Answer

Students with beards are adults or close to adulthood according to the Shariah. It is haraam to submit to the order of the evil teacher who forces his students to shave their beards. The Muslim students should rather accept being expelled from school. They should not disobey Allah Ta'ala at the behest of the evil teacher. Such a teacher should not be allowed to lead the Salaat. The teacher's act of compelling students to shave their beard is kufr, the effect of which is irtidaad. The teacher has become a murtadd. Salaat behind him is not valid.
