Yahya related to me from Malik, from Muhammad ibn Abd ar-Rahman, from Sulayman ibn Yasar, that when the Messenger of Allah, may Allah bless him and grant him peace, set out for hajj in the year of the farewell hajj, some of his companions went into ihram to do hajj on its own, some of them combined hajj and umra, and some went into ihram to do umra on its own. Those who had gone into ihram to do hajj, or hajj and umra together, did not come out of ihram, whils tthose who had gone into ihram to doumra (on its own) came out of ihram.
