Muwatta Malik #771

Yahya related to me from Malik, from Abu'l-Aswad Muhammad ibn Abd ar-Rahman, fromUrwa ibn az-Zubayr, that A'isha, the wife of the Prophet, may Allah bless him and grant him peace, said, "We set out with the Messenger of Allah, may Allah bless him and grant him peace, in the year of the farewell hajj, and some of us went into ihram to do umra, some of us went into ihram to do hajj and umra, and some of us went into ihram to do hajj on its own. The Messenger of Allah, may Allah bless him and grant him peace, went into ihram to do hajj on its own. Those who had gone into ihram to do umra came out of ihram (after doing umra). Those who had gone into ihram to do hajj (on its own), or to do both hajj and umra, did not come out of ihram until the day of the sacrifice."
