Musnad Abu Ya'la al-Mawsili 155:119

Abu Khaythama narrated to us, Sufyan ibn 'Uyaynah narrated to us, from al-Zuhri, from Abu Salamah, from Abu Hurayrah, that the Messenger of Allah (may Allah bless him and grant him peace) said: "Allah has not listened to anything as He has listened to a Prophet who recites the Quran with a melodious voice."
