Musnad Ahmad 26437 — Hadith of Hafsah, Mother of the Believers

It is narrated from Hazrat Hafsa that in the year of the Farewell Pilgrimage, the Prophet (peace be upon him) instructed his noble wives to come out of the state of Ihram. Someone submitted in the presence of the Messenger (peace be upon him), "O Messenger of Allah, what is this matter that people have come out of their Ihram, but you have not come out of the Ihram of Umrah?" The Prophet (peace be upon him) replied, "In fact, I had tied the garland around the neck of the sacrificial animal and had already trimmed my hair, therefore I cannot come out of Ihram until I have completed the Ihram of Hajj."
