«كُتْرِ الْقُولْ دَلِيلْ عَلَى قِلِّةِ الْعَقْلْ»

The saying links excessive talk to poor judgment. Someone who chatters without restraint, filling every pause with words, is taken to be showing that they lack the composure and discernment of a thoughtful person, who chooses carefully when speaking is worthwhile.

The Arabic sets 'abundance' against 'scarcity' in a neat contrast, and the closing words qōl (saying) and ʿaql (mind) echo each other in sound, giving the line a balanced, memorable shape that suits a pointed reproach.

Used to rebuke someone who talks endlessly, boasts, or interrupts, or to counsel restraint in speech, often to younger people. Because it frames measured words as wisdom, aiming it at a specific person implies they are foolish and may give offense.
