The Quran Verse
Surah 28:76:
Indeed, Qarun was from the people of Moses, but he tyrannized them. And We gave him of treasures whose keys would burden a body of strong men...
The Biblical Contrast (Numbers 16):
In the Bible, Korah is a Levite who leads a political and religious rebellion against the authority of Moses and Aaron. He is swallowed by the earth for his insolence regarding the priesthood, not primarily for his wealth.
The Quran transforms Korah into "Qarun," a symbol of extreme material greed.
This transformation serves a specific polemical purpose in 7th-century Mecca: it targets the wealthy Quraysh elite. By characterizing the biblical rebel as a "billionaire" whose wealth could not save him, the Quran uses a modified biblical figure to deliver a contemporary socio-economic warning. It moves the focus from clerical rebellion (biblical) to material arrogance (Quranic).
