From Sahih Muslim (Hadith 2960):
Abu Musa (Allah be pleased with him) reported:The Messenger of Allah (May peace be upon im) had sent me to Yemen and I came back In the year in which he (the Holy Prophet) performed the (Farewell) Pilgrimage. Allah's Messenger (may peace be upon, him) said to me: Abu Musa, what did you ' say when you entered into the state of Ihram? I said: At thy beck and call; my (Ihram) is that of the Ihram of Allah's Apostle (May peace be upon him). He said: Have you brought the sacrificial animals? I said: No. Thereupon he said: Go and circumambulate the House, and (run) between al-Safa' and al-Marwa and then put off Ihram. The rest of the hadith is the same
