Musannaf Ibn Abi Shayba 3:6363

Waki’ narrated to us, he said: ‘Abdullah bin Sa’id bin Abi Hind narrated to us, he said: I heard Abu Salamah bin ‘Abd al-Rahman saying: I heard Abu Hurairah saying: The Messenger of Allah (peace and blessings of Allah be upon him) said: "Allah has not listened to anything as He listens to a prophet who chants the Quran, reciting the Quran aloud."
