It is narrated from Sayyiduna Bara’ bin ‘Azib (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) was asked:“From which animals should one avoid for sacrifice?”The Messenger of Allah (peace and blessings be upon him) indicated with his fingers and said,“One should avoid four.”Sayyiduna Bara’ bin ‘Azib (may Allah be pleased with him) would also indicate with his fingers and say,“My hand is smaller than the hand of the Messenger of Allah (peace and blessings be upon him).”(They are:) A lame animal that cannot walk, a one-eyed animal whose defect is obvious, a sick animal whose sickness is apparent, and an extremely thin animal that has no marrow.

It is narrated from Hazrat Nafi that Sayyiduna Abdullah bin Umar (may Allah be pleased with them both) would avoid those sacrificial animals which were not musinnah and those which had any limb missing.
Imam Malik (may Allah have mercy on him) said: I like this narration very much.

It is narrated from Bashir bin Yasar that Abu Burdah bin Niyar offered his sacrifice before the Messenger of Allah (peace be upon him) had performed his. So the Prophet (peace be upon him) ordered him to offer another sacrifice. He said, "O Messenger of Allah! I have nothing left except a one-year-old goat." The Prophet (peace be upon him) said, "Sacrifice that."

It is narrated from Hazrat Ubadah bin Tamim that Uwaymir bin Ashqar performed the sacrificial slaughter before the dawn of the tenth day. And when he mentioned this to the Messenger of Allah, peace and blessings be upon him, he ordered him to offer another sacrifice.

It is narrated from Nafi‘ that Abdullah bin Umar (may Allah be pleased with them both) once performed the sacrifice in Madinah, so he ordered me to buy a horned goat and to slaughter it on the day of Eid al-Adha at the Eid ground. I did so, and then the slaughtered goat was sent to Abdullah bin Umar (may Allah be pleased with them both). When he had his head shaved—at that time he was ill and did not come for the Eid prayer. Nafi‘ said: Abdullah bin Umar (may Allah be pleased with them both) used to say that shaving the head is not obligatory upon the one performing the sacrifice, but Abdullah bin Umar (may Allah be pleased with them both) still had his head shaved.

It is narrated from Sayyiduna Jabir bin Abdullah (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) had previously forbidden keeping the meat of sacrificial animals for more than three days. Then afterwards he said: "Eat, and give (to others), and give for the sake of Allah, and make provisions from it and keep it."

It is narrated from Sayyiduna Abdullah bin Waqid (may Allah be pleased with him) that the Messenger of Allah (peace and blessings of Allah be upon him) forbade eating the meat of sacrificial animals after three days. Abdullah bin Abi Bakr said: I narrated this to Umrah bint Abdur Rahman, and she said: Sayyiduna Abdullah bin Waqid (may Allah be pleased with him) has spoken the truth. I heard from Sayyidah Aisha (may Allah be pleased with her) that some people from the desert came during Eid al-Adha in the time of the Messenger of Allah (peace and blessings of Allah be upon him), so he said: "Keep the meat for three days and give the rest for the sake of Allah after that." The people said to him: O Messenger of Allah! Before this, people used to benefit from their sacrifices, and they used to store their fat and make water skins from their hides. He (peace and blessings of Allah be upon him) said: "What is the matter?" They said: Now you have forbidden keeping the meat of the sacrifice for more than three days. He (peace and blessings of Allah be upon him) said: "I did that because some poor people from the desert had come. Now eat the meat of the sacrifice, give charity, and store it."

Sayyiduna Abu Sa'id Khudri (may Allah be pleased with him) returned from a journey, and the people of his household placed meat before him. He said: "See, is this the meat of sacrifice?" They said: "It is indeed from the sacrifice." Sayyiduna Abu Sa'id (may Allah be pleased with him) said that the Messenger of Allah (peace and blessings be upon him) had forbidden this. The people said: "After you, the Messenger of Allah (peace and blessings be upon him) gave another ruling in this matter." Sayyiduna Abu Sa'id (may Allah be pleased with him) left the house to investigate this matter. When news reached him that the Messenger of Allah (peace and blessings be upon him) had said: "I had forbidden you from eating the meat of sacrifice after three days, but now eat, give in charity, and store it. And I had forbidden you from making nabidh in certain vessels, now make it in whichever vessel you wish, but whatever causes intoxication is forbidden. And I had forbidden you from visiting graves, now visit the graves, but do not utter anything evil from your mouths (i.e., words of disbelief or ungratefulness)."

It is narrated from Sayyiduna Jabir bin Abdullah (may Allah be pleased with him) that we performed sacrifice in the year of Hudaybiyyah: a camel on behalf of seven people, and a cow was slaughtered on behalf of seven people.

It is narrated from Hazrat Amarah bin Sayyad that Ata bin Yasar informed him, having heard from Sayyiduna Abu Ayyub Ansari (may Allah be pleased with him), who used to say: We used to offer one goat as sacrifice on behalf of ourselves and all our household, but later, considering it a matter of pride, people started offering one goat for each individual.
