What are the obligatory conditions for sacrificial slaughter of animals to be valid? Also what are the Sunnah recommendations to follow?
I am asking about the details relevant to the actual act of slaughter and not for example the requirements regarding the animal such as its type, age and health etc.
Please provide Quran, Hadith or Fiqh references. I keep hearing of stuff like 'can't use a serrated knife', 'offer the animal water' and 'cut the four vessels of the throat', but I am unsure about the references for these or how these are derived.
