Sahih al-Bukhari 1559

It is related that Abu Musa said, "The Prophet, may Allah bless him and grant him peace, sent me to some people in the Yemen and I returned to find him at al-Batha'. He asked, 'With what intention did you go into ihram?' I replied, 'I went into ihram with the same intention as the Prophet, may Allah bless him and grant him peace.' He said, 'Do you have a sacrificial animal with you?' I said, 'No.' He instructed me to do tawaf of the House and to go between Safa and Marwa. Then he instructed me to come out of ihram. I went to a woman of my people who combed my hair or washed my head. Then when 'Umar came, he said, 'If we go by the Book of Allah, it commands us to complete hajj and 'umra. Allah says, "Perform the hajj and 'umra for Allah," (6:196) and if we take the sunna of the Prophet, may Allah bless him and grant him peace, he did not come out of ihram until he had sacrificed his camels.'"
