`A'isha (Allah be pleased with her) reported

We went with the Messenger of Allah (ﷺ) (in his) Farewell Pilgrimage near the time of the appearance of the new moon of Dhul-Hijja. The Messenger of Allah (ﷺ) said: He who amongst you intends to put on Ihram for `Umra may do so; had I not brought sacrificial animals along with me, I would have put on Ihram for `Umra. She (further said). There were some persons who put on Ihram for `Umra, and some persons who put on Ihram for Hajj, and I was one of those who put on Ihram for `Umra. We went on till we reached Mecca, and on the day of `Arafa I found myself in a state of menses, but I did not put off the Ihram for `Umra. I told about (this state of mine) to the Messenger of Allah (ﷺ), whereupon he said: Abandon your `Umra, and undo the hair of your head and comb (them), and put on Ihram for Hajj. She (`A'isha) said: I did accordingly. When it was the night at Hasba and Allah enabled us to complete our Hajj, he (the Holy Prophet ) sent with me `Abd al-Rahman b. Abu Bakr, and he mounted me behind him on his camel and took me to Tan`im and I put on Ihram for `Umra, and thus Allah enabled us to complete our Hajj and `Umra and (we were required to observe) neither sacrifice nor alms nor fasting.
