Rafi' bin Khadij (RAA) narrated that the Prophet ( صلی اللہ علیہ وسلم ) said: "You may eat an animal which is slaughtered by any means which causes the blood to gush out as long as Allah's Name is mentioned over it, except for the tooth and the claw (not allowed to be used). The tooth is a bone and the claw is the knife of the Abyssinians (Ethiopians)." Agreed upon.

Jabir bin Abdullah (RAA) narrated, "The Messenger of Allah ( صلی اللہ علیہ وسلم ) prohibited beating a tied-animal to death." Related by Muslim.

Shaddad bin Aus (RAA) narrated that the Messenger of Allah ( صلی اللہ علیہ وسلم ) said: "Verily, Allah has prescribed proficiency in all things. Thus, if you kill, kill in the least painful manner you can; and when you slaughter an animal, do it in the best possible way; and any of you should sharpen his blade so that the animal may be spared from the suffering of the slaughtering."

Abu Sa'id Khudri (RAA) narrated that the Messenger of Allah ( صلی اللہ علیہ وسلم ) said: "The (legal) slaughtering of the fetus is included when its mother is slaughtered." Related by Ahmad and Ibn Hibban graded it as Sahih.

Ibn 'Abbas (RAA) narrated that the Messenger of Allah ( صلی اللہ علیہ وسلم ) said: "A Muslim's name is sufficient for him, so if he forgets to mention Allah's name when he slaughters an animal, he should mention Allah's name, then eat it." Related by Ad-Daraqutni but there is a weak narrator in its chain. Also there is Muhammad bin Yazid bin Sinan in its chain who is truthful but had a weak memory. 'Abdur Razzaq transmitted it with a sound chain of narrators on the authority of Ibn 'Abbas but it is not connected up to the Prophet ( صلی اللہ علیہ وسلم ). Abu Dawud narrated a similar hadith that reads, "The slaughtering (of an animal) by any Muslim is Halal (lawful) whether or not he mentioned Allah's name over it." Its narrators are reliable.

Anas bin Malik (RAA) narrated, "The Messenger of Allah ( صلی اللہ علیہ وسلم ) used to sacrifice two two-horned rams, mention Allah's name and say the Takbir (Allahu Akbar or Allah is the Most Great), and place his foot on their sides." In another version, "He slaughtered them with his own hands." Another version has, "Two fat rams,' and another has, 'two precious rams.' Agreed upon. In a version by Muslim, 'and would say Bismillah and Allahu Akbar.' Muslim has also reported on the authority of 'Aishah (RAA), "Allah's Messenger ( صلی اللہ علیہ وسلم ) ordered a horned ram with black legs, a black belly and black around its eyes, and it was brought for him to sacrifice and he said to 'Aishah (RAA), "Aishah, get the knife." Then he said, "Sharpen it with a stone." When she had done so he took it, then taking it (the ram) he placed it on the ground and slaughtered it. He then said, "Bismillah (In the name of Allah), O Allah, accept it from Muhammad, Muhammad's family and from Muhammad's Ummah (followers)." (Then he sacrificed it.'

Abu Hurairah (RAA) narrated that Allah's Messenger ( صلی اللہ علیہ وسلم ) said: "He who can afford it but did not offer a sacrifice must not come near our place of prayer." Related by Ahmad and Ibn Majah. Al-Hakim graded it as Sahih. Other Imams said that it is Mawquf (i.e. it is not connected to the Prophet ( صلی اللہ علیہ وسلم ).)

Jundub bin Sufian (RAA) narrated, 'I witnessed (the prayer of) 'Idul Ad-ha with the Messenger of Allah ( صلی اللہ علیہ وسلم ) and when he finished his prayer with the people, he looked at a sheep which had been sacrificed, so he said, "Anyone who has sacrificed before the prayer must sacrifice another goat instead (of the one which he slaughtered before the prayer) and if anyone has not sacrificed he should do so in Allah's name." Agreed upon.

Al-Bara bin 'Azib (RAA) narrated Allah's Messenger ( صلی اللہ علیہ وسلم )stood among us and said, "There are four types of sacrificial animals, which are not permitted: A one-eyes animal which has obviously lost the sight of one eye, a sick animal which is obviously sick, a lame animal which obviously limps, and an old animal which has no marrow." Related by Ahmad and the four Imams. At-Tirmidhi and Ibn Hibban graded it as Sahih.

Jabir (RAA) narrated that Allah's Messenger ( صلی اللہ علیہ وسلم ) said: "Sacrifice only a full-grown animal unless it is difficult for you, in which case you should sacrifice a (six to ten month old) sheep." Reported by Muslim.
