«زَي عَفْرِيتِ الْقَيَّالَهْ مَا يِنْهَدِّشْ»

The saying pictures a spirit that roams in the scorching hours of midday, when everyone else is overcome by heat and sinks into rest. Such a creature is never worn down by fatigue or forced to settle, so comparing someone to it marks them as endlessly active and immune to exhaustion.

In practice the comparison most often lands on people whose tireless energy is spent on harm or mischief. It can still describe a diligent, untiring worker, yet the demonic image tends to tilt it toward disapproval of someone who never stops making trouble.

Say it of someone whose energy never flags, especially a person who keeps stirring up trouble despite every reason to stop. It can be teasing praise for a hard worker, but listeners will often hear a reproach aimed at relentless mischief.
