I heard Hishām b. Hakīm b. Hizām reciting sūra al-Furqān (Qur’ān, 25) in a different manner from my way of reciting it, and God’s messenger had taught me to recite it. I nearly spoke sharply to him, but I delayed till he had finished, and then catching his cloak at the neck I brought him to God’s messenger and said, “Messenger of God, I heard this man reciting sūra al-Furqān in a manner different from that in which you taught me to recite it.” He told me to let him go and told him to recite. When he recited it in the manner in which I had heard him recite it God's messenger said, “Thus was it sent down.” He then told me to recite it and when I had done so he said, “Thus was it sent down. The Qur’ān was sent down in seven modes of reading, so recite according to what comes most easily.”
‘Abīda al-Mulaikī who was a Companion reported God’s messenger as saying, "Do not make the Qur’ān a pillow,* but recite it as it deserves to be recited during the night and the day. Recite it aloud, chant it and consider its contents, perhaps you may prosper; but do not seek to get reward for it in this world, for it provides rewards.”(i.e., in the next world)

I heard a man who recited, and as I had heard the Prophet reciting differently I took him to the Prophet and told him and noticed that he gave a disapproving look. He then said, “Both of you are doing it well, so do not disagree, for your predecessors disagreed and perished.”
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.
