What is the ruling on inflating the skin after slaughter to facilitate flaying?

The questioner : In some countries, when they slaughter a sheep, they make a cut in its leg and begin to inflate it, blowing air into the skin until the skin separates from the meat, and during the inflation, they strike the sheep.

The Shaykh : Yes.

The questioner : Is this thing...?

The Shaykh : This is not permissible, especially when it is sold and its meat is sold, because this inflation beautifies the meat; when a person sees it, he says, "This is fatty and good meat." Therefore, we consider it deception. However, if it is done merely to facilitate flaying, there is nothing wrong with it, but it must not be inflated until after the animal has died.

The questioner : Yes, after death. But, Shaykh, it is now well known, for example, in a certain country that this inflation is standard; it is impossible to slaughter a person in that town without them knowing that the Saturday will be in this channel.

The Shaykh : Well, if there is no deception, as long as it is known to the people, there is no deception, although leaving it is better. Because some people do not know how to flay. I saw, with my own eyes, a man—I did not witness his action on the day of 'Id al-Adha, after the prayer and the sermon, he slaughtered twenty sheep before noon and finished them all, and this is strange. Yes, if I slaughter a sheep from the 'Id prayer, it appears at the call to noon prayer, and yet the skin does not settle from the cuts.
