The Cow - 2:188
Do not eat your money unjustly among yourselves. And do not bribe officials/managers with the intention of taking the people´s money unjustly.
The end of those who unjustly eat people's money/property:
The Cow/2:275
"Those who eat usurious money rise up like one who is struck by the devil. This is because they say, "Usury is like shopping". But Allah has made shopping lawful and usury unlawful. And whoever receives a reminder from his Lord and desists, he may keep what he has earned in the past, and his affair is up to Allah. As for those who continue, they are the inhabitants of Hell, and they will abide therein forever."
The Women/4:10
Those who eat the property of orphans unjustly will fill their bellies with fire and will end up in Hell.
