He named what the worker does in order to achieve benefit and prosperity as cultivation in a metaphorical sense. He differentiated between the works of the two types of workers:

That whoever works for the Hereafter is successful in his work and his good deeds are multiplied. And whoever's work is for this world is given something of it, not what he desires and seeks. This is his provision that has been allotted to him and he has finished with it, and he has no share at all in the Hereafter. It was not mentioned in the context of the worker for the Hereafter that he has a share in this world, on the condition that his allotted provision will certainly reach him, due to the insignificance of that in comparison to what he is striving for in the purity of his work and his success in the ultimate return.
