Sayyidah Aishah (may Allah be pleased with her) said: We set out with the Messenger of Allah (peace and blessings be upon him) for the Farewell Hajj. Some of us said the talbiyah for Hajj, some for Umrah, and some for both Hajj and Umrah, and the Messenger of Allah (peace and blessings be upon him) said the talbiyah for Hajj. Whoever had said the talbiyah for Umrah left ihram, and whoever had said the talbiyah for Hajj, or for both Hajj and Umrah, did not leave ihram until the Day of Sacrifice, when he left it.
