What is the state of the muqtadis' Salaat if the Imaam uses a loudspeaker?

Answer

It is not permissible to use a loudspeaker for Salaat and Khutbah notwithstanding the validity of the Salaat. The Imaam and all those who support the loudspeaker for Salaat are sinful. Those who are not in support of this bid'ah are not blameworthy. Their Salaat is correct. The Muqtadis Salaat will not be Makrooh or Faasid if the Imaam uses a loudspeaker.
