In Surah Baqarah, verse 24, Allah says:
Translation: […] Fear the fire whose fuel is people and stones (Surah Baqara: 2:24)
Why stones, you ask? Because idols are made of stones. Subhanallah. People and stones will fuel the Hellfire, the way gasoline fuels cars. May Allah protect us all from that horrid end, ameen.
