Musannaf Ibn Abi Shaybah 4060 — Sweeping mosques

Al-Muttalib bin Abdullah bin Hantab said: Sayyiduna Umar (may Allah be pleased with him) came to the Mosque of Quba on his horse and prayed in it. Then he said to his servant: "O Yarfa'! Bring me a palm-branch broom." When he brought it, Sayyiduna Umar tucked up his garment and swept the mosque.
