Abdullah bin Mughaffal (may Allah be pleased with him) said: I saw the Messenger of Allah (peace and blessings be upon him) on the day of the Conquest of Makkah; he was reciting Surah al-Fath [Surah al-Fath: 1] in a melodious voice. Abdullah bin Mughaffal (may Allah be pleased with him) also recited it in a beautiful voice. Abu Iyas (may Allah have mercy on him) said: Were it not that I fear people would gather around me, I too would recite in the manner of the Messenger of Allah (peace and blessings be upon him).
(b) Abu Ubayd (may Allah have mercy on him) said: This is the interpretation of his (peace and blessings be upon him) saying: "Beautify the Qur'an with your voices when you recite it."
