Lesson 82 traveling for work is blessed:

Allah says in the Quran meaning and other ones who travel the land seeking from the preference of Allah.

This shows us getting wealth is tied to traveling the earth. The value of things changes based on their location. Take the example of a city which produces a lot of rice and little to no wheat. People who live here have more rice than they can eat, and anyone can buy a sack full of rice. For one silver coin in the city.

Now, imagine you took a thousand sacks of rice, filled an entire ship with them, and sailed to a far away city bearing the pain of travel in this far away city. Wheat is local produce and rice is a delicacy. And people buy one sack of rice for one gold coin. So you sell the rice in the city and load up your ship with a thousand sacks of wheat and sail back, making lots of profits.

The value of people also changes based on their location.
