«كُل فُولَه وْلَهَا كَيَّالْ»

In its bare form, the saying holds that nothing escapes valuation: every item, even a single bean, has someone whose task is to gauge it, and that judgment fits the thing's own condition and worth rather than a single fixed scale.

The picture is of dry goods being measured out for trade. By naming one bean, about the smallest and humblest unit imaginable, the proverb stresses that even a trifling thing is weighed up, and that the appraisal answers to what the thing actually is.

Suited to remarks that something, however small, ordinary or modest, will still find someone to assess it on its own terms; the bean stands for any minor item whose worth is judged according to its particular state.
