Assalamualaikum and Salam Aidiladha to all Muslims.
Alhamdulillah, Alhamdulillah, Alhamdulillah, all praises ONLY to ALLAH because of His continuous blessings, we are still able to sujud because of Him and still embrace this beautiful deen, Islam till today.
As we all know, we are just celebrated Aidiladha on previous Sunday and as an ibadah, all competent Muslims are encouraged to perform Qurban or slaughtering selected animals. The meats from the slaughtered animals are distributed to the poor and the needs, while the main aim from this ibadah is only to cherish the Taqwa in our soul. As in al-Quran:
“Their meat will not reach Allah , nor will their blood, but what reaches Him is piety from you. Thus have We subjected them to you that you may glorify Allah for that [to] which He has guided you; and give good tidings to the doers of good.” Al-Hajj:37
But today, I will like to talk a little about the methods in slaughtering animals. During my preparation years in Malaysia, an Ustazah of ours held a feast at her house, but before we have to eat, we are taught and independently, we had to slaughter some chickens. According to Islamic methods, we have to cut only the big vessels (carotid artery and jugular vein), and it is MAKRUH to just cut through the neck (and yes, there are some of us end up with headless chickens). So, I wonder what are the differences?
Now, let’s talk about some physiology.
When the big vessels are cut open, it will cause massive blood loss and the brain craves for more blood supply, since it is not supplied by the responsible vessels. The nervous system will react by causing the centralization of blood supply to this vital organ (all blood from different organs are collected and heart pumps more vigorously). But the result is, more blood expelled through the carotid artery right. In the end, the animal die with, literally speaking, no blood stays in the meats. So the meat is fresher.
Imagine if we just slaughter off the head. Yes, the blood is still emerged out through the open vessels BUT not as maximum because the nervous system is not activated due to the disconnection of spinal cord. So the meat is a little bit lesser in quality.
Hence, because of His guidance, we are always provided with fresh meats, free from blood that may carry some pathogens that might harm us.
