They got a shock when their imaam recited al-Faatihah in English
Question

                What should be done if a brother puts himself forward to lead the salat, and then he begins to read the Al-fatiha in english. Should those behind him leave the salat or continue to pray with him.
Praise be to Allah. You should say “Subhaan 
          Allaah!” to him. If he pays attention, then all well and 
          good, otherwise you should leave the salaah and pray on your own. It 
          is not permissible for you to continue praying behind him. And Allaah 
          knows best.
