Musnad Abi Ya'la 5451 — a man from the land of Syria (al-Sham) came

It is narrated from Salim bin Abdullah bin Umar (may Allah have mercy on him) that a man from the land of Syria (al-Sham) came and sat with Sayyiduna Abdullah bin Umar (may Allah be pleased with them both) while I was also with him. The man asked him: "O Abu Abd al-Rahman, what do you say about combining Umrah with Hajj, that is, Tamattu' (enjoying the benefit of Umrah until Hajj)?" Sayyiduna Abdullah bin Umar (may Allah be pleased with them both) said: "For whoever does it, it is a very fine and beautiful deed." The man said: "But your father (Sayyiduna Umar (may Allah be pleased with him)) used to forbid it?" On hearing this, Sayyiduna Abdullah bin Umar (may Allah be pleased with them both) became angry and said: "Woe to you! Tell me, if my father forbade it and the Messenger of Allah (peace and blessings be upon him) did it himself, would you follow the command of the Messenger of Allah (peace and blessings be upon him) or the command of my father?" He said: "No (not my father's command), rather the command of the Messenger of Allah (peace and blessings be upon him)." He said: "Then indeed the Messenger of Allah (peace and blessings be upon him) did it. Now go about your business."
