It wasnarrated that 'Aishah said:
"We went out with the Messenger ofAllah (ﷺ) for Hajj in three ways. Some of us began the Talbiyah forHajj and 'Umrah together, some of us began the Talbiyah for Hajj onits own, and some of us began the Talbiyah for 'Umrah on its own.Those who began the Talbiyah for Hajj and 'Umrah together did notexitIhram at all until they had completed the rites of Hajj. Thosewhobegan the Talbiyah for Hajj on its own did not exit ihram at alluntilthey had completed the rites of Hajj. And those who began theTalbiyahfor 'Umrah on its own circumambulated the House and ranbetween Safaand Marwah, then whatever had been forbidden to thembecamepermissible until the time for Hajj came."
