What is the fuel of Hellfire in the Quran?

The Quran explicitly states that the fuel (Waqood) of Hellfire is "men and stones" (Quran 2:24, 66:6). Classical scholars like Ibn Kathir explain 'men' refers to the disbelievers, and 'stones' refers to the idols they worshipped, signifying the totality of their false beliefs becoming the source of their punishment.

Why does the Quran say stones will be fuel for Hell?

According to classical commentators, the stones that fuel Hell are primarily the idols that people worshipped instead of Allah. This demonstrates ultimate divine justice, where the false deities, which could not benefit or harm, are shown to be worthless by becoming fuel for the torment of their own worshippers.

Who are the people that will be fuel for the Fire in Islam?

The Quran identifies the fuel of the Fire as those who reject faith (disbelievers). Specifically, Surah 3:10 states, "Indeed, those who disbelieve... it is they who are the fuel of the Fire." This includes those who engage in idolatry and deny the messages of the prophets, making their own beings the substance of their punishment.

Fuel in Islam - Quranic Concept of Waqood

At a Glance

According to search-discovered classical Islamic scholarship, the Quranic term Waqood (وَقُود), meaning fuel, is a powerful eschatological concept primarily used to describe the substance that sustains the fire of Hell (Jahannam). The Quran explicitly states in verses like 2:24 and 66:6 that the fuel of this fire is "men and stones." Tafsir masters such as Ibn Kathir and Al-Jalalayn explain that the 'men' are the disbelievers who rejected divine guidance, and the 'stones' are the very idols they worshipped. This serves as a profound illustration of divine justice, where the objects of false worship and the worshippers themselves become the material of their own eternal punishment. The linguistic root of Waqood, relating to 'kindling' or 'igniting,' emphasizes that these elements are not passive but actively feed the flames. This synthesis across Quranic verses establishes Waqood not merely as a substance, but as a dire warning against disbelief and a testament to the ultimate futility of idolatry.

💎 Deeper Insights

The Fuel of Hell is Self-Perpetuating: Synthesizing the verses reveals a chilling concept of divine justice. The 'fuel' is not an external substance but the disbelievers and their false gods themselves. This implies a self-perpetuating punishment where the very agents and objects of sin become the eternal source of their own torment, a perfect and inescapable circle of consequence.

— Ibn Kathir, Al-Qurtubi

The Ultimate Inversion of Purpose: The stones carved into idols were meant to be objects of reverence, intercession, and salvation. Search grounding across tafsirs reveals that by making them 'fuel,' Allah performs the ultimate inversion of their intended purpose. They go from being perceived saviors to being instruments of damnation, a powerful theological statement on the futility of shirk.
