Sayyiduna Abu Umamah (may Allah be pleased with him) said: A slave girl of Sayyiduna Abu Mas'ud Uqbah bin Amr (may Allah be pleased with him) was grazing goats, and one of the goats was on the point of death, so she broke off a stone of marwah (flint) and slaughtered it with it. Then she brought it to Uqbah bin Amr (may Allah be pleased with him) and told him, and he said to her: Take it, just as it is, to the Messenger of Allah (peace and blessings be upon him). The Messenger of Allah (peace and blessings be upon him) said to her: "Did you cut the jugular veins?" She said: Yes. He said: "Whatever cuts the veins (suffices for slaughter), except biting with a tooth or tearing with a nail."
