Sahih Bukhari | Volume 5 | Hadith Number 681

Narrated by Hafsa
(The wife of the Prophet) The Prophet ordered all his wives to finish their Ihram during the year of Hajjat-ul-Wada. On that, I asked the Prophet "What stops you from finishing your ihram?" He said, "I have matted my hair and garlanded my Hadi. So I will not finish my Ihram unless I have slaughtered my Hadi."
