“...And there are those who bury gold and silver and spend it not in the way of Allah: announce unto them a most grievous penalty. On the Day, when it will (all) be heated in the fire of Hell, and with it will be branded their foreheads, their flanks, and their backs. (and it will be said unto them) : This is the (treasure) which you buried for yourselves: taste you, then, the treasures you buried” ( Surat at-Tawba : 34-35 )
