Is it fine to use the microphone for zuhr and asr salaah when there are only about 70 to 80 musallees?
It should be understood that the Imaam is required to raise his voice in Salaah to the extent of his congregation whereby the persons standing in the last row (Saff) of the Salaah should be able to adequately hear his voice without any form of uncertainty or doubt left in their minds particularly with regard to the change and transmission from one posture to another. If this can easily be achieved without the use of a microphone then the use of a microphone in such an instance is unwarranted and unnecessary.
