In the name of allah, the Beneficent, the Merciful What is sin in Islam?

THE STUNNING

Two aspects of the stunning part of the slaughtering procedure need to be examined.

First: its ruling in general and second: whether or not it kills the animal before it actually gets slaughtered.

The ruling of stunning in the Islamic Fiqh is that it is Makrooh or disliked for it causes pain to the animal and it is not a recommended part of the Islamic slaughter way which requires that the animal be treated gently.

We took the second question (whether stunning kills the animal before it is slaughtered) to three professionals in the meat business: Dr. Fawzee As Sayed, a veterinarian and a USDA meat inspector in the area of Fresno, California; Amin Attia, owner of Halal Products International, who has been in the business of meat slaughtering, domestically and for export, for more than ten years; he is also based in Fresno, California; and Ahmad Fallah, owner of International Market in Fort Collins, Colorado. Mr. Fallah has more than thirteen years of experience in the meat industry and is presently completing his Ph.D. in veterinary medicine.

All of these three confirmed the fact that the stunning procedure definitely causes the animal to die in a short period of time (a function of the animal health and other factors) if left without slaughtering. When asked about he percentage of animals that die before slaughtering, each one had a different answer. Dr. As Sayed insisted the delays in the production lines are very minimal an that the percentage of animals who die before being slaughtered is less than one percent. He also said that inspectors can and do identify the animals and order them removed from the production line. Mr. Attia is of the same option as Dr. As Sayed but he believes that the percentage may be as high as three or four percent. Mr. Fallah, however, strongly ascertains based on his experience in many slaughterhouses that the percentage of animals who die prior to being slaughtered is around fifteen (15%) percent. Any estimate, he said, of less than ten percent (10%) is unrealistic.
IF THE MEAT IN A NON-MUSLIM MARKET WAS SLAUGHTERED BY PEOPLE OF THE BOOK BUT WE KNOW THAT SOME OF IT CAME FROM ANIMALS THAT WERE STUNNED AND DIED PRIOR TO BEING SLAUGHTERED, IS THE MEAT LAWFUL FOR MUSLIMS TO CONSUME?

Most scholars are of the opinion that if the percentage of the dead animals is small (2 or 3%) then one can eat that meat because the probability of it being dead is minimal, but if that percentage increases to ten (10%) or more then one can not eat the meat. Dr. Aburrahman Abul Khaliq, however, is of the opinion that one can not eat that meat at all for the default rule when it comes to eating is the meat is Haram until it is proven to be Halal.
