It is narrated from Sayyiduna Abu Sa'id al-Khudri (may Allah be pleased with him) that a man's she-camel was about to die, so he slaughtered it with a wooden peg (watad). I asked him: Did you slaughter it with an iron blade? He said: No, rather with wood. Then that man asked the Prophet (peace and blessings be upon him) about it, and he (peace and blessings be upon him) ordered him to eat its meat. This hadith has a sahih (authentic) chain, and its chain is also sahih on the condition of the two Shaykhs (Bukhari and Muslim). I did not rule it sahih on their condition only because Imam Malik (may Allah have mercy on him) narrated it in "al-Muwatta" from Zayd bin Aslam in mursal form (without the Companion).

It is narrated from Sayyiduna Zayd bin Thabit (may Allah be pleased with him) that a wolf wounded a goat with its teeth, so the people slaughtered it with a sharp stone (marwah), and the Prophet (peace and blessings be upon him) granted permission to eat it. This hadith has a sahih (authentic) chain, but the two Shaykhs (Bukhari and Muslim) did not record it.
