Bukhari

Hadith Commentary:
Nahr is specific to the camel, while other animals are laid down and slaughtered.
The camel is stabbed with a dagger in its chest while standing; this is called nahr.
Sacrifice (qurbani) is among the symbols (sha‘a’ir) of Islam.
According to the situation and place, without doubt, performing nahr and sacrifice at the Eid ground is also Sunnah; however, under current circumstances, this Sunnah should be performed at one’s home or at designated places. Islam has provided allowance for adapting to circumstances.

Hadith Commentary:
(1)
Shah Waliullah Muhaddith Dehlawi rahimahullah writes in the explanation of the chapter headings of Bukhari:
The prescribed (masnun) practice is that the camel, cow, etc., should be slaughtered at the Eid ground (Eidgah), and what some people are doing contrary to this—i.e., when they return from the Eidgah and then perform the sacrifice (nahr and dhabh) at their homes—this act is non-sunnah, and it happens due to laziness.

(2)
Undoubtedly, performing the sacrifice at the Eidgah is sunnah, but in view of circumstances and conditions, this sunnah can also be fulfilled at one's homes or at designated places, although it is better that this act be done at the Eidgah.
The rulers of Islam also used to perform the sacrifice at the Eidgah.
There are many benefits in this.
Firstly, it is an expression of the symbols (sha‘a’ir) of Islam; secondly, there is benefit for the poor, for when the sacrifice is performed at the Eidgah, due to necessity some meat will go to the home, but the rest will be distributed among the poor, and also given to needy people along the way. However, performing the sacrifice at home is not prohibited, because nowadays Eid prayers are generally performed in public parks, and it is not permitted to slaughter sacrificial animals there and spread filth.
And Allah knows best.

Hadith Commentary:
Hazrat Nafi‘ bin Sarjis was the freed slave of Hazrat Abdullah bin ‘Umar (radi Allahu anhuma).
He is among the renowned elders regarding hadith.
Imam Malik (rahimahullah) states that when I hear a hadith through the chain of Nafi‘, I become completely unconcerned with any other narrator.
He passed away in the year 117 AH.
Most of the narrations in Imam Malik’s book *Muwatta’* are from him.
Rahimahullah, may Allah have vast mercy upon him.
The hadith narrated by Nafi‘ from Hazrat Ibn ‘Umar (radi Allahu anhuma) is what is intended here.

Hadith Commentary:
(1)
Imam Malik rahimahullah holds the view that the imam should prominently slaughter his sacrifice at the Eid prayer ground so that others may follow his example. Some individuals have exaggerated to the extent that an imam who does not slaughter at the place of sacrifice is not worthy of leading or being followed in prayer.

(2)
In any case, Imam Bukhari rahimahullah has narrated this hadith in two ways: one as mawquf (attributed to a Companion) and the other as marfu‘ (attributed to the Prophet sallallahu alayhi wa sallam). The marfu‘ hadith serves as evidence for the previously mentioned mawquf narration.

(3)
Abdullah ibn Umar radi Allahu anhu, as a follower of the Sunnah, used to slaughter his sacrifice at the very place where the Messenger of Allah sallallahu alayhi wa sallam used to slaughter his. In any case, it is recommended (mustahabb) that the imam, in particular, perform the sacrifice at the Eid prayer ground so that others are encouraged.

(4)
In the present era, it is better to perform the sacrifice at a designated place for slaughter so that the environment remains clean.

(1) The purpose was to instill enthusiasm among the people. After seeing you (the Prophet sallallahu alayhi wa sallam) perform the sacrifice, no one who possessed the ability could remain negligent. Even now, this practice is recommended (mustahabb) for the imam, but it is not obligatory. Imam Malik has considered it obligatory, but there is no evidence for its obligation.

(2) "Dhabh (slaughter) or nahr (sacrifice by piercing the throat)"—cows, goats, sheep, rams, etc., are slaughtered (dhabh), whereas camels are sacrificed by nahr.

It is as if they would not take the camel to the Eid prayer ground, but rather slaughter it within the city itself. If it were a smaller animal, they would take it along, because slaughtering a large animal takes more time and requires more helpers; therefore, it is better to do it at home.

Benefits and Issues:
➊ The term "musalla" refers to the open ground where the Eid and rain-seeking (istisqa) prayers were performed.

➋ The wisdom in slaughtering (sacrifice) at the Eid ground is that both the rich and the poor gather there, thus making distribution easier. However, it is not obligatory to slaughter at the Eid ground; it can also be done at home.
