Musannaf Ibn Abi Shaybah 31921 — Teaching the Quran: how many verses

Abu Abd al-Rahman said: One of the companions of the Prophet (peace and blessings be upon him) who used to teach us the Qur'an narrated to us. He said: "The Companions used to learn ten verses from the Messenger of Allah (peace and blessings be upon him), and they would not learn the next ten verses until they knew what these verses contained of practice and knowledge." He said: "We learned both knowledge and practice."
