And We placed the scales of justice for the Day of Resurrection, so no soul will be treated unjustly at all.

     And We placed the scales of justice for the Day of Resurrection, so no soul will be treated unjustly at all. And if there is [even] the weight of a mustard seed, We will bring it forth. And sufficient are We as accountant.
