The Holy Quran, as a comprehensive source of guidance, offers an integrated framework for human life, including lifestyle and nutrition. This study aims to clarify the criterion of halal food in the light of Quranic teachings through a semantic approach, examining whether this criterion transcends mere jurisprudential permissibility and is rooted in a deeper concept.

Using a descriptive–analytical method and structural semantics—particularly semantic field analysis—the research investigates this issue. The findings show that the central determining concept is tazkiyah. Lexically denoting growth and purity, and terminologically referring to purification of the soul from vices and its adornment with virtues, tazkiyah forms a semantic network with concepts such as *taqwa*, *ṭayyib*, falah, and guidance, while opposing notions like fujur and rijs.

By employing the expression “halālan ṭayyiban,” the Quran elevates the standard of desirable food beyond outward permissibility. The ṭayyib quality of food signifies intrinsic and spiritual purity and its positive influence on the human soul. This criterion encompasses three dimensions: purity in the source and essence of food, lawful acquisition, and consumption. Thus, in the Quranic view, true halal food facilitates human growth, purity, and spiritual elevation.
