Is reward or punishment divisible such that the reward for giving one pound differs from the reward for giving two pounds, and is the punishment for stealing a pen equal to the punishment for stealing a car?

Donating one pound is not like donating two, for the reward of the first might be greater due to circumstances surrounding it. As for the proverb mentioned: "If you steal, steal a camel," its meaning is corrupt. The correct (saying) is: "Do not steal small or large," and the sin of the thief varies according to what was stolen, and the time and place.
