i would like to ask does the friday kutbah have to include the arabic kutbah even if majority of the people do not understand arabic?
if so, what to do if the person delivering the kutbah does not know the arabic and simply offers a english kutbah then leads salah without knowing the arabic was mandatory? is the jummuah prayer still accepted or has this jummuah prayer been nullified

thank you
