Glossary of Islamic terms

These terms are used throughout GSCS halal certification without translation. Their meaning and role in the certification process are explained below.

Halal

What it means
Permissible under Islamic law. The baseline requirement: an ingredient, product or process must be halal to be eligible for certification at all.
Where it matters in certification
Every product, ingredient and process GSCS certifies must be halal — it is the certification's core claim, checked at ingredient classification, desk review, audit and panel decision.

Haram

What it means
Forbidden under Islamic law — the opposite of halal (e.g. pork, its derivatives, and improperly slaughtered meat).
Where it matters in certification
Any haram ingredient or process disqualifies a product outright. Ingredient classification screens for it before an application can proceed to audit.

Syubhah

What it means
Of doubtful or uncertain halal status — neither clearly halal nor clearly haram, usually because its source or processing cannot yet be verified.
Where it matters in certification
An ingredient classified as syubhah cannot be accepted on presumption: it triggers a request for supplier documentation (e.g. a halal certificate or source declaration) before it can be cleared for the formulation.

Najs

What it means
Ritually impure substance under Islamic law. It has three severity categories: mughallazah (major — e.g. contact with a dog or pig), mutawassitah (moderate — e.g. most other impurities), and mukhaffafah (minor — e.g. a male infant's urine before solid food).
Where it matters in certification
A najs finding during a facility audit determines what corrective action is required, up to and including sertu, before halal production may proceed on that equipment or in that area.

Sertu

What it means
The prescribed ritual purification process — seven washes, one of them with clean soil/earth — required to remove najs mughallazah contamination from equipment, utensils or premises.
Where it matters in certification
Required before halal production begins on equipment or premises previously used for non-halal production or contaminated with najs mughallazah. Auditors verify sertu was performed and documented, not merely claimed.

Dhabihah

What it means
The Islamic method of slaughtering permitted animals: a swift cut to the throat by a qualified Muslim slaughterman, invoking Allah's name, while the animal is alive and treated humanely.
Where it matters in certification
For any meat or poultry product, the audit programme verifies dhabihah compliance directly at the point of slaughter — method, personnel qualification and animal welfare are all checked on-site, not taken on the supplier's word.

Tasmiyah

What it means
The invocation of Allah's name ("Bismillah") pronounced at the moment of slaughter — a required element of valid dhabihah.
Where it matters in certification
Auditors confirm tasmiyah is pronounced for each individual slaughter act, not once for a whole batch. A lapse invalidates the dhabihah for that animal specifically.

Khamr

What it means
Intoxicating alcohol or liquor. Its presence, or the presence of any khamr-derived ingredient, renders a product non-halal.
Where it matters in certification
Formulation and ingredient review specifically screen for khamr content or khamr-derived ingredients, including trace carry-over from processing aids or flavourings.

Halalan Toyyiban

What it means
The combined standard of being both halal (permissible) and toyyiban (wholesome, clean, of good quality) — halal status alone is not enough.
Where it matters in certification
GSCS's certification decision certifies both: halal permissibility and toyyiban wholesomeness. Food safety, hygiene and quality findings from audits feed into the panel's final decision alongside pure halal status.
