According to search-discovered classical Islamic scholarship, the concept of Tasmiyah (التسمية)—the act of mentioning Allah's name—is a foundational principle that sanctifies an action and transforms it into an act of worship. As elucidated by classical commentators like Ibn Kathir and Al-Qurtubi in their tafsir of Surah Al-An'am (6:118), Tasmiyah is not merely a ritual but a profound declaration of Tawheed (monotheism). It explicitly distinguishes the believer, who acknowledges Allah as the sole Provider and Legislator, from pagan practices of making arbitrary prohibitions and invoking other names, which the Quran (6:138) deems a 'slander against Him'. The linguistic analysis from sources like Al-Tabari confirms its root in 'Ism' (name), signifying a deliberate act of invocation. Therefore, the synthesis of Quranic verses and scholarly analysis establishes Tasmiyah, especially over sustenance, as a critical expression of faith that makes food permissible (Halal) and invites divine blessing (Barakah) into a believer's life.
