«يَا قَاري العِلْمْ عَند الجَاهلين حَرَامْ»

The expression warns a learned person that pouring scholarly talk into an audience with no grounding in the subject accomplishes nothing. Such exchanges drain time and cheapen the knowledge itself, because the listeners cannot engage with it, weigh it, or answer it meaningfully. Its vernacular spelling reflects spoken pronunciation and gives it an everyday, conversational flavor.

Its sharp wording, including the word for 'forbidden,' is forceful exaggeration, not a literal religious or legal ruling, and is no call to withhold instruction. Patiently guiding someone who wants to learn is a different matter. The saying aims at fruitless discussion with those who neither know nor can respond, and advises reserving serious intellectual exchange for fitting company.

Suitable when cautioning someone against spending effort debating or discussing specialized matters with people who lack the background to follow or value them. It serves as a gentle reminder to choose one's audience wisely, not as a dismissal of learners who are open to instruction.
