Musnad Ahmad 788:64

'Abd al-Rahman narrated to us, Sufyan narrated to us, from Qays ibn Muslim, from Tariq ibn Shihab, from Abu Musa, who said: I arrived to the Messenger of Allah (peace and blessings of Allah be upon him) while he was at al-Batha'. He said: "With what did you enter into Ihram?" I said: "With an Ihram like the Ihram of the Prophet (peace and blessings of Allah be upon him)." He said: "Did you bring a sacrificial animal (Hady)?" I said: "No." He said: "Perform Tawaf around the House and between al-Safa and al-Marwah, then exit Ihram."
