Musannaf Ibn Abi Shaybah 4860 — A man who sleeps through his portion

Abu Bakr bin Muhammad bin Amr bin Hazm said: A man asked permission to come in to Sayyiduna Umar (may Allah be pleased with him) at midday. He did not give him permission for a long time; then he was given permission. Sayyiduna Umar said to him: I used to recite a portion of the Qur'an at night; I could not recite it last night, so I was reciting it at this time.
