It is narrated from Umm al-Mu'mineen Sayyidah Aisha (may Allah be pleased with her) that we set out with the Messenger of Allah (peace and blessings of Allah be upon him) in the year of the Farewell Pilgrimage, so we entered into ihram for ‘Umrah. Then the Messenger of Allah (peace and blessings of Allah be upon him) said:“Whoever has a sacrificial animal with him should combine the ihram of Hajj and ‘Umrah, and then not exit ihram until he has completed both.”Sayyidah Aisha (may Allah be pleased with her) said: I arrived in Makkah while in a state of menstruation, so I did not perform tawaf nor the sa’i between Safa and Marwah, and I complained to the Messenger of Allah (peace and blessings of Allah be upon him). He (peace and blessings of Allah be upon him) said:“Undo your hair and comb it, and abandon the ‘Umrah, and enter into ihram for Hajj.”I did as I was told. When we had completed Hajj, the Messenger of Allah (peace and blessings of Allah be upon him) sent me with Abdur Rahman bin Abi Bakr to Tan‘eem. I performed ‘Umrah, and the Messenger of Allah (peace and blessings of Allah be upon him) said:“This ‘Umrah is in place of your previous ‘Umrah.”So those who had entered into ihram for ‘Umrah became lawful after performing tawaf and sa’i, then performed another tawaf for Hajj when they returned from Mina. And those who had entered into ihram for Hajj, or for both Hajj and ‘Umrah together, performed only one tawaf.
