It is narrated from Sayyiduna Rafi' bin Khadij (may Allah be pleased with him) that he said: I saw the Messenger of Allah (peace and blessings be upon him) eat a shoulder of meat; when he finished, he wiped his fingers on the wall, then he prayed Asr and Maghrib and did not perform ablution (wudu).
