«طُورِ الْحَرْتْ مَا يِتْكَمِّمْشْ»

The image comes from farm life. An ox pulling a plow through the field has no grain within reach, so there is no reason to strap a muzzle on it. The muzzle belongs to the animal trampling harvested grain on the threshing floor, where it could stop and eat.

Applied to people, the saying objects to needless restrictions. It targets someone who bans or limits another person in a matter that poses no real risk while that person is busy at some task, implying that the caution is misplaced and the restraint serves no purpose.

Say it when someone fusses over or restricts a worker in a task that offers no chance for misuse, pointing out that the precaution is pointless. It suits gentle pushback against excessive supervision or suspicion aimed at someone simply getting on with honest labor.
