«شُفْتِشِ الْجَمَلْ؟ قَالْ: وَلَا الْجَمَّالْ»

The saying praises or describes total discretion about a secret. Asked only about one obvious detail, the camel, the speaker volunteers a denial of more, its driver, showing they will give away nothing, not even a clue leading back to the hidden matter. The animal and its handler are figurative; the point is refusing information.

It can also gently mock exaggerated secrecy. The reply is so sweeping that it borders on comic, like someone who claims ignorance of a large, unmistakable animal and the man leading it. The overstatement shows the speaker has decided to know nothing whatsoever. A related form denies seeing either the camel or its handler, with the same sense.

Use it playfully about someone who stays tight-lipped when pressed for details, or to signal that you will reveal nothing at all. It suits informal exchanges about confidences, rumors, or sensitive matters that should not be passed on. A flatly literal rendering can lose the joke of the overreaching answer.
