How is the legal Islamic slaughter (dhahb) performed for chickens, sheep, cattle, and camels? How many times must the knife be used in the slaughter of camels? And must one wait for the animal to bleed before cutting the jugular vein?

The method of Shar'i (Islamic legal) slaughter entails obligations and recommended acts, including:

Firstly: Obligations: 1. The slaughterer must be a Muslim or a person of the Book (Jew or Christian), whether an adult, a discerning child, or a woman. 2. To invoke Allah's name over the animal when intending to slaughter it. 3. To shed the blood by cutting the two jugular veins (the two thick veins surrounding the windpipe and esophagus), and the preponderant opinion is that these are sufficient to render the animal permissible. If normal slaughter is difficult for a wild animal or one that has fallen into a well, it is sufficient to shed blood from any part of its body.

Secondly: Recommended Acts: 1. Facing the Qiblah with the animal when slaughtering. 2. Treating the animal with kindness, by doing everything that brings it comfort, such as concealing the knife from its sight, using a sharp instrument, and passing it with force and speed to minimize pain.

Thirdly: Method of Slaughter and its Specifics: 1. For camels: The Sunnah is to slaughter them while standing with their left foreleg tied at the hollow between the chest and the base of the neck. 2. For cattle and sheep: The Sunnah is to slaughter them while they are lying on their side, with the slaughterer placing his foot on the side of their neck to gain control. 3. For chickens: There is no specific Sunnah regarding the method of slaughtering them. Their slaughter is valid if performed by a Muslim or a person of the Book, the name of Allah is invoked over them, and blood is shed.
