about the verse: It is We who have dispensed among them their livelihood, 'Allah, the Exalted, told us that employment is one of the means of people's livelihood. He, in His wisdom, diversified their aspirations, motivations, and other states. Thus, He made man's employment of one another one of the means of people's livelihood ... If every one of us was forced to build for himself, make his own furniture, and produce everything himself... the world's conditions would not be bearable and people would not be able to endure them, and would find them impossible. But he ensured its management by diversifying their aspirations so that everyone performs for others that which is Employment compatible with his own capacity, in order for some of them to be served by others and for their conditions to be sound.'
