It is narrated from Sayyiduna Jabir bin Abdullah (may Allah be pleased with him), he says: I performed Eid al-Adha with the Messenger of Allah (peace and blessings be upon him). When he (peace and blessings be upon him) finished, a ram was brought to him. When he (peace and blessings be upon him) was about to slaughter it, he (peace and blessings be upon him) said: "In the name of Allah, and Allah is the Greatest. O Allah! Indeed, this is on my behalf and on behalf of those from my ummah who have not offered sacrifice."

It is narrated from Sayyida Aisha (may Allah be pleased with her) that the Messenger of Allah (peace and blessings be upon him) ordered for a ram with horns, whose legs were black, the area around its eyes was also black, and its belly was black as well. So it was brought so that the Prophet (peace and blessings be upon him) could offer it as a sacrifice. Then the Prophet (peace and blessings be upon him) said: "Aisha! Bring the knife." Then he said: "Sharpen it with a stone." So Sayyida did as he said. Then the Prophet (peace and blessings be upon him) took the knife and caught the ram, laid it down to slaughter it, and said: (In the name of Allah, O Allah! Accept this on behalf of Muhammad (peace and blessings be upon him), the family of Muhammad (peace and blessings be upon him), and the Ummah of Muhammad (peace and blessings be upon him)).

Imam Nafi' says that Sayyiduna Abdullah bin Umar (may Allah be pleased with them both) used to slaughter his sacrificial animal at the Eidgah on the day of sacrifice and would state that the Noble Prophet (peace and blessings be upon him) used to do the same.

It is narrated from Sayyiduna Abdullah bin Umar (may Allah be pleased with them both) that the Noble Prophet (peace and blessings be upon him) used to perform sacrifice (nahr) in Madinah Munawwarah on the day of Eid al-Adha; if he did not perform nahr, he would slaughter (dhabh).

It is narrated from Sayyiduna Ibn Umar (may Allah be pleased with them both) that the Messenger of Allah (peace and blessings be upon him) stayed in Madinah Munawwarah for ten years, and during this period, he offered sacrifice every year.

Abu al-Khair says that it is narrated from an Ansari man, may Allah be pleased with him, that the Messenger of Allah, peace and blessings be upon him, wanted to lay down his sacrificial animal for slaughter, and he, peace and blessings be upon him, said to a man: Assist me a little in this matter of sacrifice. So he assisted him, peace and blessings be upon him.

It is narrated from Sayyida Umm Salama (may Allah be pleased with her) that the Noble Prophet (peace and blessings be upon him) said: When the first ten days of Dhul-Hijjah begin, then a person who intends to offer a sacrifice should neither touch his hair nor his body.

(Second chain) The Messenger of Allah, peace and blessings be upon him, said: Whoever intends to offer a sacrifice should neither trim his nails nor shave his hair during the first ten days of Dhu al-Hijjah.

(Third chain) The Noble Prophet, peace and blessings be upon him and his family, said: Whoever intends to offer a sacrifice in the month of Dhu al-Hijjah should not touch his hair or nails.

It is narrated from Sayyiduna Abdullah bin Amr (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said to a man: I have been commanded regarding the Day of Sacrifice (Yawm al-Adha); Allah Almighty has made this day a festival for this Ummah. The man said: What is your opinion if I have only a goat belonging to my son, should I sacrifice it? The Prophet (peace and blessings be upon him) said: No, rather on the day of sacrifice, cut your hair, trim your nails, shorten your mustache, and shave the hair below the navel; this act will be considered a complete sacrifice for you in the sight of Allah Almighty.
