Musannaf Ibn Abi Shaybah 28381 — Reports on the midday nap

Abd al-Rahman bin Abi Layla says that Sayyiduna Khawwat bin Jubayr (may Allah be pleased with him), who was a Companion who fought at Badr, said: "Sleeping in the early part of the day is foolishness, sleeping in the middle of the day is natural disposition, and sleeping in the last part of the day is stupidity."
