Answer: Praise be to Allaah.
Making one’s voice beautiful when reciting Qur’aan is something that is prescribed and was enjoined by the Prophet (صلى الله علیه وسلم). The Prophet (صلى الله علیه وسلم) listened to the recitation of Aboo Moosaa al-Ash’aree (رضي الله عنه) and liked it, and he told him,
“You have been given a melodious voice like that of Daawood.” [Muslim, Salaatul-Musaafireen, 793]
On this basis, if the Imaam of a mosque imitates a person who has a beautiful voice and recites beautifully in order to make his own voice and recitation of the Book of Allaah more beautiful, this is something which is prescribed for him and for others, because it moves the worshippers praying behind him, and makes them focus, listen and pay attention to the recitation. Allaah bestows His bounty on whomsoever He wills and He is the owner of great bounty.
