On the authority of Abu Huraira (may Allah be pleased with him), who said: The Messenger of Allah said: “Allah the Almighty is good and accepts only that which is good. Allah has commanded the Faithful to do that which He commanded the Messengers, and the Almighty has said: “O ye Messengers! Eat of the good things, and do right..” (Quran 23:51). And Allah the Almighty has said: “O ye who believe! Eat of the good things wherewith We have provided you..” (2:172). Then he mentioned [the case of] a man who, having journeyed far, is disheveled and dusty and who spreads out his hands to the sky [saying]: O Lord! O Lord!-while his food is unlawful, his drink is unlawful, his clothing unlawful, and he is nourished unlawfully, so how can he be answered!” (Muslim).

On the authority of Abu Ya'la Shahddad ibn Aus, the Messenger of Allah said: “Verily Allah has prescribed proficiency in all things. Thus, if you kill, kill well; and if you slaughter, slaughter well. Let each one of you sharpen his blade and let him spare suffering to the animal he slaughters” (Muslim).

In an incident narrated by Rafi' bin Khadij, the Prophet told Muslims who wanted to slaughter some animals using reeds, “Use whatever causes blood to flow, and eat the animals if the Name of Allah has been mentioned on slaughtering them...” (Bukhari).

Narrated Abu Thalaba: Allah's Messenger forbade the eating of the meat of beasts having fangs (Bukhari).

Narrated Ibn Umar: The Prophet cursed the one who did Muthla to an animal (i.e. cut its limbs or some other part of its body while it is still alive (Bukhari).
