Bismillah.
Narrated Nafi':
'Abdullah (bin 'Abdullah) bin 'Umar said to his father, "Stay here, for I am afraid that it (affliction between Ibn Zubair and Al-Hajjaj) might prevent you from reaching the Ka'ba." Ibn 'Umar (radiallaahu `anhu) said, "(In this case) I would do the same as Allah's Apostle (sallallaahu `alayhi wasallam) did, and Allah has said, 'Verily, in Allah's Apostle (sallallaahu `alayhi wasallam), you have a good example (to follow).' So, I make you, people, witness that I have made 'Umra compulsory for me." So he assumed lhram for 'Umra. Then he went out and when he reached Al-Baida', he assumed Ihram for Hajj and 'Umra (together) and said, "The conditions (requisites) of Hajj and 'Umra are the same." He, then brought a Hadi from Qudaid. Then he arrived (at Mecca) and performed Tawaf (between Safa and Marwa) once for both Hajj and 'Umra and did not finish the lhram till he had finished both Hajj and 'Umra.
A similar Hadith has been covered before. Read it here.
According to the commentator Ibn Battaal, Imaam Bukhari mentioned this Hadith here in order to show the opinion of Ibn `Umar (radiallaahu `anhu) concerning the hadi (animal of sacrifice). He used to say that the hadi has to be bought/brought from outside of the boundaries of haram. And in later posts, we'll see that it must be sacrificed inside haram.
It is not Sunnah if you have done ‘Umrah to buy a sheep and slaughter it; the Sunnah is to bring a sheep with you from your country or at least from the miqaat or the closest point outside the sanctuary, according to some scholars, and this is called driving the hadiy. But offering a sacrifice after ‘Umrah without having brought the animal with you is not part of the Sunnah. End quote.
