She asked the Messenger of Allah ﷺ, "Why is it that the people have exited the state of ihram, but you have not exited from your umrah?"He replied, "I have matted my hair and garlanded my sacrificial animal, so I will not exit ihram until I have slaughtered it."
أنها قالت لرسول الله ﷺ: ما شأن الناس حلوا ولم تحلل أنت من عمرتك؟ فقال: إني لبدت رأسي، وقلدت هديي فلا أحل حتى أنحر.
Malik narrated it in Hajj (180) from Nafi, from Abdullah bin Umar, with this chain, and I have mentioned it. Bukhari narrated it in Hajj (1566), and Muslim in Hajj (1229:176), both of them through Malik, with this chain, similarly.
