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.
