Sahih Al Bukhari 5.678: Bk 64.418
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−Tan`im 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).

Sahih Muslim Bk 7, Number 2764: Bk 15.119
'A'isha (Allah be pleased with her) said: We went with the Messenger of Allah (may peace be upon him) during the year of the Farewell Pilgrimage. We entered into the state of Ibrim for Umra. Then the Messenger of Allah (may peace be upon him) said: Who has the sacrificial animal with him, he should put on Ihram for Hajj along with Umra. and should not put it off till he has completed them (both Hajj and Umra). She said: When I came to Mecca. I was having menses, I neither circumambulated the House, nor ran between as−safa' and al−Marwa. I complained about it to the Messenger of Allah (may peace be upon him) and he said: Undo your hair, comb it, and pronounce Talbiya for Hajj, and give up Umra (for the time being), which I did. When we had performed the Hajj, the Messenger of Allah (way peace he upon him) sent me with Abd al−Rabman b. Abu Bakr to Tan'im saying: This is the place for your Umra. Those who had put on Ibrim for Umra circumambulated the House, and ran between al−safa' and al−Marwa. They then put off Ihram and then made the last circuit after they had returned from Mina after performing their Hajj, but those who had combined the Hajj and the Umra made only one circuit (as they had combined Hajj and 'Umra).
