—for stripping the fruit, harvesting it, and then measuring it with the legally prescribed measure would impose great hardship, so estimation through khars was deemed sufficient.
Thus, God-fearingness and the legal obligations He has laid down are commensurate with a person’s ability and capacity.
The juristic maxim states that whenever attaining certainty is impossible or excessively difficult, acting on predominant conjecture is enough, and the Sharia offers many examples of this principle.
