Abdullah bin Umar reported,

He did not release himself from any of the restrictions of ihram until he completed his pilgrimage, sacrificed his offering on the Day of Sacrifice, and performed tawaf around the House. Then he released himself from all the restrictions of ihram. Those among the people who had brought offerings and driven the sacrificial animals did the same as the Messenger of Allah ﷺ had done.

Sahih

عن عبد الله بن عمر، قال

ثم لم يحلل من شيء حرم منه حتى قضى حجه، ونحر هديه يوم النحر، وطاف بالبيت، ثم حل من كل شيء حرم منه. وفعل مثل ما فعل رسول الله ﷺ من أهدى وساق الهدي من الناس.
