Nasai

Other narrations state that he would sacrifice one ram on his own behalf and the other ram on behalf of those poor people of his ummah who could not offer a sacrifice themselves. This is a particular distinction of the Messenger of Allah (sallallahu alayhi wa sallam), because for an ordinary member of the ummah, the sacrifice suffices only for his own household. Therefore, to derive from this hadith the permissibility of offering a sacrifice solely on behalf of the deceased—while the one performing the sacrifice does not include himself in it—is questionable. And Allah knows best.

Hadith Commentary:
It is Sunnah to recite this supplication at the time of slaughtering the sacrificial animal.
«إِنِّي وَجَّهْتُ وَجْهِيَ لِلَّذِي فَطَرَ السَّمَوَاتِ وَالْأَرْضَ، حَنِيفًا مُسْلِمًا، وَمَا أَنَا مِنَ الْمُشْرِكِينَ، إِنَّ صَلَاتِي، وَنُسُكِي، وَمَحْيَايَ، وَمَمَاتِي لِلَّهِ رَبِّ الْعَالَمِينَ، لَا شَرِيكَ لَهُ، وَبِذَلِكَ أُمِرْتُ، وَأَنَا أَوَّلُ الْمُسْلِمِينَ، بِسْمِ اللَّهِ، واللَّهُ أَكْبَرُ، اللَّهُمَّ مِنْكَ، وَلَكَ عَنْ مُحَمَّدٍ، وَأُمَّتِهِ» If one is performing the sacrifice on behalf of another, then one should say: "Allahumma taqabbal ‘an (so-and-so, son of so-and-so)," mentioning their name in place of (so-and-so, son of so-and-so).
After reciting this supplication, the animal should be slaughtered with a sharp knife.

Hadith Commentary:
(1)
Before slaughtering, the knife should be properly sharpened and kept hidden from the animal. Then, after reciting "Bismillah, Allahu Akbar," the animal should be slaughtered.
(2)
It is preferable to perform the sacrifice (qurbani) with one's own hand, but another person may also do it, as during the Farewell Pilgrimage (Hajjat al-Wada'), the Messenger of Allah (sallallahu alayhi wa sallam) performed the sacrifice on behalf of his noble wives. They only became aware of it when the meat reached them.
(Sunan Ibn Majah, Kitab al-Manasik, Hadith: 2981)

Hadith Commentary:
(1)
Hazrat Rafi‘ radi Allahu anhu narrates that when the Messenger of Allah sallallahu alayhi wa sallam intended to offer a sacrifice, he would purchase two fat, healthy rams.
(Majma‘ al-Zawa’id: 4/21)
It should be noted that these narrations do not specify that fat animals are superior to other animals. However, if it is said that a fat animal is superior because it contains more meat and thus the poor will benefit more from it, then this is certainly reasonable.

(2)
Imam Ibn Qudamah rahimahullah states that it is Sunnah for the sacrificial animal to be fat and excellent, because Allah the Exalted has said:
“Whoever honors the symbols of Allah, then it is truly from the piety of the hearts.”
(al-Hajj: 32)
By honoring it is meant that the animal should be fat and respected, because this is a cause of great reward and increased merit.
(al-Mughni: 13/367)

Hadith Commentary:
It is best that the one offering the sacrifice performs the slaughter himself and touches the animal.

Hadith Commentary:
(1)
It is better that the sacrificial animal be slaughtered with one’s own hand, but this is not a condition for the sacrifice. If someone is unacquainted with slaughtering, he may appoint another person as his agent to perform the slaughter on his behalf.

(2)
The preferable method of slaughtering is that the animal be laid on its left side, then the one performing the slaughter should place his right foot on its right side so that it is easier for him to hold the knife with his right hand and grasp the neck with his left hand. This is the practice among Muslims. If someone, out of ignorance, laid the animal on its right side, then the slaughter and the consumption of the animal are still valid. And Allah knows best.

Hadith Commentary:
This has already been explained earlier that the animal should be laid down on its left side, then the one performing the slaughter should place his right foot on its neck so that it becomes easy to hold the knife in the right hand and grasp the neck with the left hand.
Muslims slaughter animals in this manner, and this method has been continuously practiced in succession.

Hadith Commentary:
Vocabulary of the Hadith:
(1)
Amlah:
Black and white,
Tending towards whiteness,
According to Al-Asma‘i, gray in color, and according to Ibn Al-A‘rabi,
Pure white,
According to another opinion, tinged with redness, that is, wheat-colored.
(2)
Aqranayn:
Having horns,
In some narrations, the addition of "castrated" is also present.

Benefits and Issues:
This hadith establishes that
the sacrificial animal should be laid down,
and while saying "Bismillah" and "Allahu Akbar," one should slaughter it with one's own hand, and the sacrificial animal should be beautiful and well-fed. The Prophet (sallallahu alayhi wa sallam) placed his foot on the animal’s neck so that it would not move and slaughtering it would be easy.
It is permissible to have someone else slaughter the animal in your presence.

Explanation:
1:
The following rulings are established from this hadith:

(1)
One should slaughter the sacrificial animal with one's own hand,
although deputizing another is also permissible.

(2)
Before slaughtering, one should recite "Bismillah, Allahu Akbar."

(3)
At the time of slaughtering, one should place one's foot on the animal's neck.

(1) It is permissible to place one’s foot on the side of the sacrificial animal at the time of slaughter. The scholars are in agreement that the animal should be laid down on its left side, and in this case, the foot will be placed on its right side.

(2) Reciting the tasmiyah (Bismillah) at the time of slaughtering the sacrificial animal is legislated. Similarly, the tasmiyah should be recited when slaughtering all animals. There is consensus on this. Along with the tasmiyah, reciting the takbir (Allahu Akbar) is also legislated, as is explicitly mentioned in other narrations.

(3) The legitimacy of slaughtering the sacrificial animal with one’s own hand is also understood from this, however, in case of necessity, someone else may be appointed as an agent.

(4) The Messenger of Allah (sallallahu alayhi wa sallam) slaughtered two rams, and from this, the legitimacy of sacrificing more than one animal is established.

(5) This blessed hadith also shows that sacrificing a beautiful animal with horns is superior, as the Messenger of Allah (sallallahu alayhi wa sallam) did; however, sacrificing an animal without horns is also valid.

(6) After laying the animal down, one should place a foot on its side so that it remains under control, the knife can be used with strength, and the animal does not move its head and hinder the slaughter, and so that it does not suffer more than necessary. This ruling is not specific to sacrifice alone.

Although one should recite “Bismillah, Allahu Akbar” over every slaughtered animal, it is especially necessary to recite it over the sacrificial animal (udhiyah), because before slaughtering it, a formal intention (niyyah) is also made, both inwardly and consciously. If one forgets to mention the name of Allah over the slaughtered animal, then that animal will still be lawful (halal); however, one should not deliberately omit it.

The order is reversed. You laid the animal down. You placed your foot on the side of its neck. You recited "Bismillah, Allahu Akbar" and slaughtered it with your blessed hand. The reason for placing the foot on the side of the neck was to restrain it so that it would not stand up during the act of slaughtering, and also so that the knife could move swiftly and forcefully. The head would not move here and there, and the animal would not suffer excessive pain.

Benefits and Issues:
➊ On the occasion of Eid al-Adha, it is obligatory for a person who has the means to offer at least one goat or ram, or a share in a cow or camel as sacrifice.

➋ It is permissible, and in fact preferable, to offer more than one sacrificial animal.

➌ A member of the household should slaughter the sacrificial animal with his own hand; however, another person may also perform the slaughter.

➍ The sacrificial animal should be of good quality and beautiful.

➎ At the time of slaughtering the sacrificial animal, it is Sunnah to recite the supplication mentioned in the following hadith, the details of which have already been discussed at the beginning.

➏ The purpose of placing the foot on the body of the animal at the time of slaughter is to keep the animal under control and to prevent it from attempting to run away.
