صحیح مسلم · Hadith 2960

Abu Musa (Allah be pleased with him) reported: I came to the Messenger of Allah ( ‌صلی ‌اللہ ‌علیہ ‌وسلم ‌ ) and he was encamping at Batha. He (the Holy Prophet) said: With what purpose have you entered into the state of Ihram? I said: I have entered into the state of Ihram in accordance with the Ihram of Allah's Apostle ( ‌صلی ‌اللہ ‌علیہ ‌وسلم ‌ ). He said: Have you brought sacrificial animals along with you? I said: No. whereupon he said: Then circumambulate the House and run between al-Safa' and al-Marwa and put off Ihram. So I circumambulated the House, ran between al-Safa' and al-Marwa, and then came to a woman of my tribe. She combed and washed my head. I used to give religious verdict (according to the above mentioned command of the Holy Prophet) during the Caliphate of Abu Bakr and also during that of 'Umar. And it was during the Hajj season that a person came to me and said: You (perhaps) do not know what the Commander of the Believers has introduced in the rites (of Hajj). I said: 0 people, those whom we have given religious verdict about a certain thing should wait, for the Commander of the Believers is about to arrive among you, so follow him. When the Commander of the Believers arrived, I said: What is this that you have introduced in the rites (of Hajj)? -where upon he said: If we abide by the Book of Allah (we find) that there Allah, Exalted and Majestic, has said: Complete Hajj and 'Umra for Allah. And if we abide by the Sunnah of our Apostle ( ‌صلی ‌اللہ ‌علیہ ‌وسلم ‌ ) (we find) that the Messenger of Allah (May peace be upon him) did not put off Ihram till he had sacrificed the animals.
