Bulugh al-Maram, Book 6, Hadith 746 (English) ⓘ

A’isha (RAA) narrated, ‘We left Madinah with the Messenger of Allah to perform the Farewell Hajj. Some of us declared Ihram to perform 'Umrah, while others declared their intentions to perform both Hajj and 'Umrah. Yet others declared their lhram to perform Hajj only. The Prophet declared Ihram for Hajj only. Those who intended 'Umrah terminated their Ihram as soon as they finished the rituals of 'Umrah. Those who intended to perform Hajj only or to combine Hajj with 'Umrah, did not terminate their Ihram until the Day of Slaughtering (i.e. the day of sacrifice or ’Idul Ad-ha).’ Agreed upon.
