Qarun was doubtless, of the people of Moses; but he acted insolently towards them: such were the treasures We had bestowed on him that their very keys would have been a burden to a body of strong men, behold, his people said to him: “Exult not, for Allah loveth not those who exult (in riches).
Qarun is identified with the Korah of the English
Bible. His story is told in Num. 16:1-35
He and his followers, numbering 250 men, rose in
rebellion against Moses and Aaron, on the ground that
their position and fame in the congregation entitled them
to quality in spiritual matters with the Priests,-that they
were as holy as any, and they claimed to bum incense at
the sacred Altar reserved for the Priests.
They had an exemplary punishment: “the earth opened
her mouth, and swallowed them up, and their houses,
and all the men that appertained unto Korah, and all
their goods: they, and all that appertained to them, went
down alive into the pit, and the earth closed upon them:
and they perished from among the congregation.”
