Musannaf Ibn Abi Shayba 3:6210

Abu Mu'awiyah narrated to us, from al-A'mash, from Muslim, who said: A man came to Masruq and said, "What do you say about a man who reads the Qur'an in a week?" Masruq said, "It is good. If you were to take a copy of the Qur'an every week and enter it into a house, it would be likely to fill it."
