«عَجَّانِ الصَّبْرْ بِيْدُوقْ»

The image is of someone kneading sabr: whoever works it in this way ends up tasting some of it. The word الصبر may be read either as patience or as the plant bearing that name, and the saying leaves both readings open.

As a general lesson, the proverb credits direct involvement with knowledge. The person who has actually taken a matter in hand comes to know it better than those who never took part in it themselves.

A colloquial saying, suitable when deferring to someone who has personally dealt with a matter, or when explaining why a participant understands its details better than people who have stayed outside it and only observed.
