Is the name "Kenza" Arabic, and is it permissible to name a girl with it?

It is permissible to name a girl "Kanza" (كنزة), as it is the feminine form of "Kanz" (كنز), meaning a precious or stored item. It was mentioned in the Hadith that "La hawla wa la quwwata illa billah" (There is no might nor power except with Allah) is a treasure from the treasures of Paradise. In Arabic, "Kanz" refers to preserved or buried wealth. The Prophet, peace and blessings be upon him, was given the two treasures: the red and the white.
