«مِنْ قَل عَقْلُهْ تِعْبِتْ رِجْلِيهْ»

The saying ties weak judgment to wasted effort. Someone who fails to think ahead keeps going back and forth on needless trips and repeated errands, so the legs figuratively pay for the mind's shortcomings: the tiredness stands for toil that poor judgment creates.

It targets a person who is busy and energetic but ignorant or careless, whose constant running about yields exhaustion rather than results. A little forethought, it implies, would spare much toil.

Said of someone who rushes about without a sensible plan, tiring themselves for little gain. Best as wry comment or mild rebuke among familiar company; aimed directly at a person, it calls them foolish and may offend.
