Is seeing diseases and a lack of personal hygiene among some worshippers, in addition to the presence of insects on the carpet, considered a valid excuse for missing prayers in the mosque, especially since the Adhan and Iqamah are only heard via external loudspeakers?

We advise you to maintain congregational prayer in the mosque and to disregard fears and whispers. Do not abandon the congregation in the mosque except for a real harm. Congregational prayer is obligatory for anyone who hears the call (adhan) or is within the range of hearing, whether inside or outside the town, provided that there is quietness and that the caller has a strong voice and the man is able to hear. The consideration is the hearing of the usual call, not through a microphone.
