Sayyidah Aishah (may Allah be pleased with her) said: We set out with the Messenger of Allah (peace and blessings be upon him), and he (peace and blessings be upon him) said: "Whoever of you wishes to make the talbiyah for Hajj and Umrah, let him do so, and whoever wishes to make the talbiyah for Hajj alone, let him do so as well." The Messenger of Allah (peace and blessings be upon him) made the talbiyah for Hajj, and other people with him (peace and blessings be upon him) made the same talbiyah; some made it for both Umrah and Hajj, some for Umrah alone, and I was among those who made the talbiyah for Umrah.
