Yahya related to me from Malik from his uncle Abu Suhayl ibn Malik that his father said, "I used to see a carpet belonging to Aqil ibn Abi Talib spread out on the day of jumua up to the west wall of the mosque. When the shadow of the wall covered the whole carpet, Umar ibn al-Khattab would come out and pray the jumua prayer." Malik, Abu Suhayl's father, added, "We would then return after the jumua prayer and take our midday sleep
