‘Abdallah b. ‘Umar said:At the Farewell Pilgrimage God’s messenger put on the ihram first for the 'umra and afterwards for the hajj, and drove the sacrificial animals along with him from Dhul Hulaifa. He first raised his voice in the talbiya for the ‘umra and afterwards he did so for the hajj, and the people along with the Prophet did it first for the ‘umra and afterwards for the hajj. Some of the people had brought sacrificial animals and others had not, so when the Prophet came to Mecca he said to the people,“Those of you who have brought sacrificial animals must not treat as lawful anything which has become unlawful for you till you complete your hajj ; but those of you who have not brought sacrificial animals should go round the House and between as-Safa and al-Marwa, clip your hair, put off the ihram, and afterwards raise your voice in the talbiya for the hajj and bring sacrificial animals. Those who cannot get sacrificial animals should fast three days during the hajj and seven days when they return to their families.”He performed the circumambulation when he came to Mecca, first touching the corner (The corner of the Ka'ba containing the Black Stone), then running during three circuits and walking during four, and when he had finished his circumambulation of the House he prayed two rak'as at the Station (Maqam Ibrahim), then giving the salutation, and departing, he went to as-Safa and went seven times between as-Safa and al-Marwa. After that he did not treat anything as lawful which had become unlawful for him till he had completed his hajj, sacrificed his animals on the day of sacrifice, gone quickly and performed the circumambulation of the House, after which all that had been unlawful became lawful for him. Those people who had brought sacrificial animals did as God’s messenger did. (Bukharl and Muslim.)
