Sunan al-Shafi'i

It is narrated from Muhammad bin Abdur Rahman, may Allah have mercy on him, that he heard (in the year when Sayyiduna Muawiyah, may Allah be pleased with him, performed Hajj) Sayyiduna Sa’d bin Abi Waqqas, may Allah be pleased with him, and Sayyiduna Dahhak bin Qais, may Allah be pleased with him, discussing the issue of Hajj Tamattu’. So Sayyiduna Dahhak, may Allah be pleased with him, said: “Only one who is not aware of the Shari’ah performs Tamattu’.” Then Sayyiduna Sa’d, may Allah be pleased with him, said: “O my nephew, what a terrible thing you have said!” He said: “Indeed, Sayyiduna Umar bin Khattab, may Allah be pleased with him, forbade Hajj Tamattu’.” So Sa’d, may Allah be pleased with him, said: “The Messenger of Allah ﷺ performed Hajj Tamattu’ and we performed Hajj Tamattu’ with him.”
