My father, the grandfather of Ubaiyah bin Rafa’ah narrates: I said, O Messenger of Allah! Tomorrow we will encounter the enemy and we do not have any knife or similar tool. The Prophet (peace be upon him) said: Sacrifice it and quickly drain its life. Whatever causes blood to flow, and Allah's name was mentioned at the time of causing blood to flow, then eat it. Except that you do not use teeth or nails. I will inform you about this: the tooth is a bone and the nail is the knife of the Abyssinians.

Hazrat Abu Idris narrates that some birds were brought to Hazrat Anas (may Allah be pleased with him), and he slaughtered them with a bamboo sliver.

Hazrat Musayyib bin Rafi was asked about slaughtering with a sharp stone or bamboo peel, so he said that there is no harm in it; eat the animal slaughtered with anything that cuts the veins, except for bone and nail.

Ibrahim and Hazrat Sha'bi say that there is no harm in slaughtering with bamboo bark or with bamboo.

Hazrat Abu Sha’sha’ was asked about the tool used for slaughtering an animal, so he said that it is permissible to slaughter with anything that cuts the veins.

Hasan says: Eat every slaughtered animal that causes blood to flow, except for teeth, nails, and bones.

Hazrat Ja'far bin Maimoon says that every thing which lets blood flow and cuts the veins makes the slaughtered animal lawful. However, the predecessors considered slaughtering with teeth and nails to be disliked, and they called them the knives of the Abyssinians.

Hazrat Zuhri says that it is permissible to slaughter with any sharp-edged iron or sharp-edged stone. Anything that cuts the veins or causes blood to flow—eat the animal slaughtered with anything except the nail and the tooth.

Hazrat Abu Raja says that we were traveling a long distance in a thorny land when one of our companions caught a rabbit. Finding nothing to slaughter it with, he slaughtered it with his fingernail, then roasted it in the hot sand and ate it. I refused to eat that rabbit. Later, I mentioned this to Hazrat Ibn Abbas (may Allah be pleased with them), and he said, "You did well by not eating it, because it was killed by strangulation."

Ibrahim says that slaughter should not be done with teeth, bone, nail, or horn.
