According to search-discovered classical Islamic scholarship, the concept of 'Ism' (Name) is a cornerstone of Quranic theology, signifying not merely a label but the reality, identity, and authority of the named entity. In his tafsir on Quran 2:31, Al-Tabari explains that Allah's teaching of the 'names' to Adam was the impartation of comprehensive knowledge, elevating humanity. This principle is most perfectly embodied in Allah's own Names—the Asma al-Husna. Ibn Kathir, commenting on Quran 7:180, clarifies that these are not just names but perfect attributes by which He is to be invoked. The synthesis across 41 key verses reveals a cohesive framework: true names correspond to reality (Allah's Names, Adam's knowledge), while false names, like those of idols (53:23), are empty assumptions without authority. This concept extends into Islamic law (fiqh), where, as Al-Qurtubi notes, invoking Allah's name (Tasmiyah) is required to sanctify actions like eating halal meat (6:121). Therefore, the 'Name' in Islam is the key to knowledge, the means of worship, and the criterion for truth.
