Tehran YJC. Religious expert says that the rituals for slaughtering animals come with biological reasons.
Hjjtoleslam
Rahmati said in interview with ISNA "Indeed all Islamic decrees follow
expediencies and vices. The same is true of ritual slaughtering, that is, if we
slaughter animals according to the rituals we will gain benefits from the meat
we use and if we do not do that and oppose the decree, surely malignancies are
directed at us.”
He added
"A while ago I read a research by a Muslim lady at a US university. They had
noticed that if an animal is ritually slaughtered, the amount of blood that comes
out of its body and circumstances of the slaughtering remove the grounds for
many diseases. But if it is slaughtered in a way other than the ritual way then
conditions will exist in the meat for a lot of diseases.
