Hello
First let me introduce my self
My name is Bambang Tri from Indonesia
Just want to give information about principle & procedures halal slaughter in Islamic law
Principle :
respiratory veins (larink) and vein rupture digestion of food (faring)
Procedures for Islamic slaughter:
1). Read Basmalah. The majority of scholars say compulsory reading Basmalah. Not read it accidentally while causing no halal slaughter of animals slaughtered, with grounded to the verse of surah al-An'am: 121 "And do you all eat the animals that did not mention the name of God to him".
According to the Shafi'i read basmalah Sunnah, on the basis of the hadith that says "Believers are Halal slaughter, read basmalah or not" (HR Ashabussunan).
2) Should be done during the day.
3) Exposes animals slaughtered in the direction of the Qibla and butchers also sunnah facing the Qibla direction.
4) Lull animals to be slaughtered on his left side and sharpen the knife used to slaughter.
Allaah a`lam.
I hope this helps.
