What is the ruling on using loudspeakers that cause the recitation to echo?

Question : The questioner says: Honorable Shaykh, what is the ruling on using loudspeakers that have a hum, through which the imam's recitation in prayer is echoed?

Answer : I hold that it is forbidden, because it necessitates adding a letter or more to the Qur'an, and this is not permissible. It is obligatory for the imams to fear Allah (Mighty and Majestic) and not to treat the Qur'an as musical instruments, like the musical instruments of the people of David, without them being musical instruments like those of the people of David. Among the attributes of the people of David was a beautiful, unadorned voice. But as for adding to it an instrument that repeats with it, such that the last letter becomes three, four, or five letters, this is, by Allah, a distortion of the Qur'an and is not permissible. It is obligatory for you, may Allah bless you, to advise the imams who do this, and say to them: You are not singing a song; you are reciting the words of Allah, so do not add a letter to it. Fear Allah in the Book of Allah, and fear Allah in the servants of Allah who treat the Qur'an as if it were musical instruments. Yes.
