Animal rennet (stated as animal or calf)

Animal rennet is taken from the stomachs of slaughtered calves, lambs or kids. Without halal certification we presume the animal was not Islamically slaughtered, so this is Haram. A halal certificate, kosher certification from an agency we accept, or proof of a halal source such as fish, zabihah or plant would change that. If the certifier allows machine slaughter or stunning, it is Doubtful · high.

Concern

From an animal, slaughter not confirmed

Known to come from an animal, and the animal's slaughter isn't confirmed. Doubtful meat is not permissible.

What clears it

  • A halal certificate from a certifier that meets our standard
  • Vegan certification (never clears alcohol)
  • A written reply from the brand, reviewed by Zulal (valid 12 months)
  • Kosher certification from an agency on our accepted list (animal ingredients and meat only; never alcohol, pork, carmine or shellac)

The important thing is that no Najas (filth) ingredient such as alcohol is used in the production of these soft drinks. However, if someone has any doubts about the use of such najis ingredients, then it is more complete for him out of wara^ to avoid such drinks.

فقد روى البيهقي عن سيّدنا عمر بن الخطاب أمير المؤمنين رضي الله عنه أنه سئل عن الجبن يصنعها المجوس وهم كفار فقال “ما وجدته في سوق المسلمين أكلته”

Islam though has a strict ruling regarding the meat. If someone has such doubt regarding the source of meat, whether it has been slaughtered Islamically or not, then it is haram to consume or eat this meat due to this doubt. This ruling of the meat becoming Haram on doubting its Islamic source is a matter of Ijma^ (scholarly concensus).
