Narrated Hafsa:

(the wife of the Prophet) I said, "O Allah's Messenger (ﷺ)! Why have the people finished their Ihram after performing the `Umra while you have not finished your lhram after your `Umra?" He said, "I have done Talbid (of my hair) and have decorated my Hadis with garlands, so I shall not finish my lhram till l have slaughtered my Hadi (animal for sacrifice).
