Some theologians interpreted weighing solely as a figure for justice, judgment, or disclosure of worth, arguing that deeds are unlike worldly physical objects and Allah needs no instrument to learn their value.
Those affirming a real balance point to the Qur’anic language of scales and reported descriptions of weighing. Allah does not require an instrument to acquire knowledge; publicly manifesting justice is a distinct matter.
The two claims must be kept apart: a real balance does not imply deficiency in divine knowledge, and admitting that its mechanism is unknown does not reduce it to metaphor.
