مسند امام احمد بن حنبل · Hadith 273

It was narrated that Abu Moosa said: I came to the Messenger of Allah (PBUH) when he was in al-Batha' and he said: "What did you enter ihram for?" I said: i have entered ihram for the same as the Prophet (PBUH) did. He said: "Have you brought a sacrificial animal?" I said: No. He said: "Circumambulate the House and go between as-Safa and al-Marwah, then exit ihram.” So I circumambulated the House and went between as-Safa and al-Marwuh, then I went to a woman of my people and she combed my hair and washed my head. I used to give fatwas on that basis during the caliphate of Abu Bakr (RA) and 'Umar. During one season when I was performing Hajj, a man came to me and said: You do not know the latest fatioa of Ameer al-Mu'mineen concerning the Hajj. I said: O people, if we gave a fatwa. Ameer al-Mu'mineen is coming to you, so follow him in perfoming Hajj. When he came i said: What is this thing that you have J introduced to the rituals [of Hajj]? He said: We see in the Book of Allah that Allah, may He be f exalted, says: "And perform properly (i.e. all the ceremonies according to the ways of Prophet Muhammad (PBUH)), the Hajj and ‘Umrah (i.e. the pilgrimage to Makkah) for Allah'' [al-Baqarah 2:196], and if we follow the Sumwh of our Prophet, he did not exit ihram until he offered the sacrifice.
