I came to the Messenger of Allah ﷺ 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 ﷺ 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 ihraam.” So I circumambulated the House and went between as-Safa and al-Marwah, 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 and ‘Umar. During one season when I was performing Hajj, a man came to me and said: You do not know the latest fatwa 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 performing Hajj. When he came I said: What is this thing that you have introduced to the rituals of Hajj? He said: We see in the Book of Allah that Allah, may He be exalted, says: `And perform properly (i.e. all the ceremonies according to the ways of Prophet Muhammad ﷺ, the Hajj and ‘Umrah (i.e. the pilgrimage to Makkah) for Allah` al-Baqarah 2:196, and if we follow the Sunnah of our Prophet ﷺ, he did not exit ihraam until he offered the sacrifice.
