If someone slaughters a chicken while it is hanging upside down, but he recites the Tasmiyah, will it be permissible to consume such a chicken?

Answer

It is not permissible to consume the chickens which are slaughtered at all these commercial plants in the haraam manner which you have explained. Furthermore, the killers at these plants generally do not recite Bismillaah.

If a Muslim at home deliberately and flagrantly without valid reason slaughters a chicken in the despicable manner described by you, then too such a chicken should not be consumed. And, if the person intentionally abandons the Islamic system of slaughter because he despises it, then he becomes a murtad. Since there is no valid reason for a person at home to kill a chicken in this haraam kaafir way, it is not permissible to consume it even if he recites Bismillaah.

The systems and institutions commanded by Allah Ta'ala and designated Sunnah by Rasulullah (sallallahu alayhi wasallam) are not hobbies to be adopted, distorted and mutilated at will and fancy. The Divine System of Thabah is a scared institution which has been categorized to be among the Shiaar (Salient Features) of Islam. The Sahaabah would refuse to consume meat if the animal slaughtered had not been faced towards the Qiblah. Imaam Maalik (rahmatullah alayh) banned a group of butchers from slaughtering goats because the animals were not facing the Qiblah and they were being slaughtered in front of one other. There is no room in Islam for SANHA, MJC and ICSA style shareetatush shaitaan (satanic slaughter). These haraam entities and purveyors of carrion have commercialized for their mercenary objectives the Devil's form of slaughter which they market in the name of Islam. It is not permissible to consume the meat of an the animal which is slaughtered in the Devil's style such as the method described by you.
