Answer: Praise be to Allaah.
There is no basis for this; it was not done at the time of the Sahaabah (رضي الله عنهم) and it is not something that they taught. It also disturbs the others who are praying with the Imaam, and disturbing other worshippers is something that is not allowed, because it distracts them.
The Prophet (صلى الله علیه وسلم) went out one night to his companions when they were praying and raising their voices in recitation. He told them not to do that and said:
According to another hadeeth:“Do not raise your voices above one another when reciting Qur’aan.” [Maalik in al-Muwatta’, as-Salaah, 29]
This indicates that everything that disturbs the people who are praying behind the Imaam is forbidden, because it disturbs the worshippers and interferes with their prayer.“Do not disturb one another and do not raise your voices above one another when reciting Qur’aan.” [Abu Daawood, as-Salaah, 1332]
With regard to the Imaam, the fuqaaha’ (رحمه الله) said: If the Imaam senses that someone has come in to join the prayer, then he should wait for him, especially in the last rak’ah in which the latecomer may catch up with the jamaa’ah, because the Prophet (صلى الله علیه وسلم) said:
But if it will cause any hardship for the members of the congregation then he should not wait, because they are more deserving of consideration than the one who has just come in, because they were there before him.“Whoever catches up with a rak’ah of the prayer has caught up with the prayer.” [Bukhaaree, al-Mawaaqeet, 580; Muslim, al-Masaajid, 607]
