Answered by Ustadh Salman Younas
Question: What is the ruling of reciting du`a and shikr aloud by an imam? It is hard for me to attain khushu’ while the dhikr and du’a are recited aloud through a mic. I feel disturbed.
Answer: assalamu `alaykum
I pray you are doing well.
The general rule is that loud dhikr and supplication (du`a) in a mosque is permissible provided that it does not disturb people who are praying and reciting the Qur’an. If it does, it would be disliked to the extent it causes disturbance. [Ibn `Abidin, Radd al-Muhtar]
The reason for this rule is that the primary purpose of the mosque is for people to perform prayer and anything that distract from this purpose would be deemed problematic. In your specific situation, you may express your concerns to the Imam if doing so does not lead to any ill-will or problems. I would suggest that instead of telling them to stop, you should propose that they do it less loudly or that they wait until people finish making up the cycle they missed with the congregation.
