Various masaail of Jamaat Salaah and Imaamat

Making jamaat

Q: Is it permissible for a mother and son to perform Salaah together in Jamaat? If so, where should the mother stand and is it necessary for the mother to give the iqaamah?

Using a microphone for Salaah

Q: Is it correct to surmise that young scholars using microphone for Salah and allowing their Salah to be broadcast in the homes for ladies to hear may be motivated by show, particularly in Fajr where the number of saffs are few and there appears to be no obvious need for microphone? If not show, what else could a reasonable rationale be?
