Al-Barā’ b. ‘Āzib told that he heard God's messenger say, "Beautify the Qur’ān with your voices, for the beautiful voice increases the beauty of the Qur’ān.”
Hudhaifa reported God’s messenger as saying, "Recite the Qur’ān with the modulations and tones of the Arabs, but avoid the modulations of those who recite love poetry and the modulations of the people of the two Books. After my death people will come who will trill when they recite the Qur’ān as is done in singing and wailing, but it will go no farther than their throats, and they and those who are charmed by their performance will be led into error.”
Baihaqī in Shu'ab al-īmān and Razīn in his book transmitted it.
Tāwūs told in mursal form that when the Prophet was asked who had the most beautiful voice for the Qur’ān and whose recitation was most beautiful he replied, "The one of whom you think when you hear him recite that he fears God.” Tāwūs added that Talq* was like that.

God's messenger came out to us when we were reciting the Qur’ān, our number including nomad Arabs and non-Arabs, and said, "Recite, for it is all good; but after you people will come who will straighten it as an arrow is straightened, seeking a reward for it in this world and not waiting for their reward in the next.”
Abū Dāwūd and Baihaqī, in Shu'ab al-īmān, transmitted it.
