«قَالُوا: الْجَمَلِ اعْقِلُوهْ. قَالُوا: هُوَّ قَايِمْ بِطِنُّهْ!»

The exchange pokes fun at an order to tie up a camel that cannot even rise and move by itself. Restraining such an animal is plainly unnecessary, so the reply turns the urgent command into a joke at the expense of whoever issued it.

Applied to people, the saying objects when someone urges harsh or tight treatment of a person who has done nothing to merit it. Rather than arguing at length, it answers the call for severity by suggesting the target gives no reason for it at all.

Say it as a sardonic rejoinder when someone insists on cracking down hard on a person who has not earned such severity, to show that the proposed strictness is out of place and that the demand itself deserves a little mockery.
