«يَا قُوْمْ لُكُمْ يُومْ»

The saying warns people not to be lulled by their present situation. Whatever ease, standing or advantage they enjoy now is temporary, because circumstances shift, and a different day is already on its way to them.

The address 'O people' turns the remark into a general reminder rather than a private complaint. It works as a humbling caution that fortune turns; the coming 'day' is a warning against complacency, not a hopeful promise of future success.

Say it to someone who is enjoying power, wealth or good luck and acting as if it will last forever. It can serve as a sober caution among friends or as a pointed rebuke to someone arrogant.
