مَا قَلَّ وَكَفَى، خَيْرٌ مِمَّا كَثُرَ وَأَلْهَى
What is little and sufficient is better than what is plentiful and distracting.
مَا means “that which,” unlike مَنْ, which can refer to a person. مِمَّا combines مِنْ + مَا and means “than what” in this comparison. خَيْرٌ expresses preference between the two cases.
وَ joins two characteristics on each side: “little AND sufficient,” “abundant AND distracting.” Omitting either كَفَى or أَلْهَى would change the central contrast.
The statement therefore does not simply say “less is good and more is bad.”
