Musannaf Ibn Abi Shaybah 16504 — A man who enters ihram for Hajj

Humayd narrates that Sayyiduna Anas (may Allah be pleased with him) said that he heard the Messenger of Allah (peace and blessings be upon him) reciting the talbiyah thus: "Labbayka bi-'umratin wa hajj (Here I am for Umrah and Hajj)" (mentioning Umrah first).
