What does Selling of Soul and Property mentioned in the verse mean?

Dear Brother / Sister,

While the verse which is translated as “Verily, Allah purchased the souls and the properties of believers in exchange for Paradise” is interpreted in Nur Collection, an exemplary anecdote is given and in the anecdote this message is placed: “The devices in those factories will be operated in my name and on my workbench. And their costs and payments will increase from one to a thousand.” The Words

During a conversation with my friends, I asked them how much soil and water cost and I could not get an answer. When I asked how much bananas cost, they told me a high value. So, when soil and water enter a tree, which is a factory of Allah, they come out in the form of bananas and gain a high value. In the same way, we give grass to a live factory called cow and we get meat and milk from it. Common beets come out of factories in the form of sugar and flower pollens become honey in beehives.
If one gives his soul and property to Allah’s workbench of orders, drawing lessons from the innumerable cautionary scenes surrounding him, he will be elevated to that supreme position called  “ala-i iliyyin” (the highest of the high ones) and will have the honor of being one of the dwellers in Heaven.

In Nur Collection, a significant lesson of truth is given by stating: “unbelief destroys the essence of humanity and transforms it from diamond into coal”. That is to say, humankind is created in the best stature (ahsan at-taqwim) like a diamond. If he strays away from the allowed way, the straight way, he is degraded to the lowest position as a punishment. That degradation is symbolized with “coal”. According to scientists, the main stone of both coal and diamond are the same. The only difference is in their way of crystallization. And from this difference, come out two opposing qualities. Just as different words can be written with the same letters, so too can reverse fruits come out from the same essence of humanity such as: believer-unbeliever, righteous-sinful, just-unjust, and modest-proud.

According to this exemplary anecdote:

The best stature: “state of being created as capable of writing the best”
The highest of the high: “the supreme position of those who can succeed in the previous one”
The lowest of the low: “the great fall and destruction of those who fail to write correctly”

The Messenger of Allah says: “The world is the field of the Hereafter”. In this sense, one needs to reach to the highest of the high, at least as a seed, in the worldly life so that it can manifest itself as that supreme position in the Hereafter. And one will deserve the position of the lowest of the low by committing sins and it will bear the fruit of that severe agony of punishment.

In summary: Both high people and low people grow in this world. And everyone tastes bliss or punishment in the afterlife based on their own deeds.
