Narrated 'Aisha: We went out with Allah's Apostle during Hajjat-ul-Wada' and we assumed the Ihram for 'Umra. Then Allah's Apostle said to us, "Whoever has got the Hadi should assume the Ihram for Hajj and 'Umra and should not finish his Ihram till he has performed both ('Umra and Hajj)." I arrived at Mecca along with him (i.e. the Prophet ) while I was menstruating, so I did not perform the Tawaf around the Ka'ba or between Safa and Marwa. I informed Allah's Apostle about that and he said, "Undo your braids and comb your hair, and then assume the lhram for Hajj and leave the 'Umra." I did so, and when we performed and finished the Hajj, Allah's Apostles sent me to At-Tanim along with (my brother) 'Abdur-Rahman bin Abu Bakr As-Siddiq, to perform the 'Umra. The Prophet said, "This 'Umra is in lieu of your missed 'Umra." Those who had assumed the lhram for 'Umra, performed the Tawaf around the Ka'ba and between Safa and Marwa, and then finished their Ihram, and on their return from Mina, they performed another Tawaf (around the Ka'ba and between Safa and Marwa), but those who combined their Hajj and 'Umra, performed only one Tawaf (between Safa and Marwa) (for both).
