it is an animal under one’s control (maqdur 'alayhi), so it is not permitted except through dhabihah (slaughtering), just like a camel or a cow.
1727 - Issue; He said: (If what is usually nahr [slaughtered by piercing the base of the throat] is slaughtered by dhabh, or what is usually slaughtered by dhabh is nahr, it is lawful).
This is the opinion of the majority of the scholars, including 'Ata', al-Zuhri, Qatadah, Malik, al-Layth, al-Thawri, Abu Hanifah, al-Shafi'i, Ishaq, and Abu Thawr. It is narrated from Dawud that camels are not made lawful except by nahr, and others are not made lawful except by dhabh, because Allah the Almighty said: "Indeed, Allah commands you to slaughter (tadhbahu) a cow" (1). A command implies obligation. He also said: "So pray to your Lord and sacrifice (wanhar)" (2). Furthermore, because the Prophet (may Allah bless him and grant him peace) performed nahr on the budn (sacrificial camels) and dhabh on the sheep, and rulings are only taken from his practice. It is narrated from Malik (3) that for camels, only nahr is sufficient, because their necks are long, so if they are slaughtered by dhabh, they are tortured by the exit of their soul. Ibn al-Mundhir said: He merely disliked it and did not forbid it. Our evidence is the saying of the Prophet (may Allah bless him and grant him peace): "Let the blood flow however you wish" (4). Asma' said: We performed nahr on a horse during the time of the Messenger of Allah (may Allah bless him and grant him peace), and we ate it while we were in Medina (5). From 'Aishah, she said: The Messenger of Allah (may Allah bless him and grant him peace) performed nahr on a single cow during the Farewell Pilgrimage (6). Also, because it is a dhakah (ritual slaughter) in the place of dhakah, its consumption is lawful, like other animals.
1728 - Issue; He said: (And if he slaughtered it and reached the vital organs, but the soul did not depart until it fell into water, or something stepped upon it, it shall not be eaten).
Meaning (1) something stepped upon it that would usually kill it. This is what al-Khiraqi mentioned, and Ahmad explicitly stated it.
