It was narrated that Abu Hayyan al-Ashja'i said:

Ibn Mas'ood (رضي الله عنه) said to me: Recite some Qur'an to me. I said to him: Aren't you the one I learned it from and aren't you the one who taught it to us? He said: I came to the Prophet (ﷺ) one day and he said: "Recite some Qur'an to me." I said: O Messenger of Allah, aren't you the one to whom it was revealed and aren't you the one from whom we learned it? He said: "Yes, but I love to hear it from someone else."
