Ayesha reported,

We set out with the Messenger of Allah ﷺ in a state of ihram for Hajj, during the months of Hajj, within the sacred precincts of Hajj, and on the nights of Hajj, until we stopped at Sarif. He came out to his companions and said, "Whoever among you does not have a sacrificial animal with him and wishes to make it an Umrah may do so, but whoever has a sacrificial animal with him should not."

Sahih

عن عائشة، قالت

خرجنا مع رسول الله ﷺ مهلين بالحج في أشهر الحج، وفي حرم الحج، وليالي الحج، حتى نزلنا بسرف فخرج إلى أصحابه فقال: من لم يكن معه منكم هدي فأحب أن يجعلها عمرة فليفعل، ومن كان معه هدي فلا.
