Musannaf Ibn Abi Shaybah 4087 — Praying on carpets and rugs

Sayyiduna Anas bin Malik (may Allah be pleased with him) said: The Messenger of Allah (peace and blessings be upon him) used to mix with us cheerfully. One day he said to a brother of mine: "O Abu Umayr! What happened to your nughayr (little bird)?" And he sprinkled water on a rug of ours and prayed on it.
