First of all, let's take the question of earning a living. Islam recognizes the natural right of man to seek his own means of subsistence according to his natural inclinations and abilities. But Islam does not give people the right to resort to any means that would spoil their moral character or distort the social order in earning a living.
Islam has clarified the difference between halal and haram in the way of earning a living. Islam has deliberately forbidden harmful methods. According to Islamic law, alcohol and all intoxicants are not only haram, but their production, sale and storage are also prohibited. Islam does not recognize adultery, prostitution and other such means as legitimate means of earning money.
Islam has also declared illegal such means of earning in which one's profit or self-interest depends on the loss and loss of others or society. Islam forbids bribery, theft, gambling, fraud and deception, stockpiling of necessities for the purpose of price rise, monopoly of one or more persons over the means of earning so as to narrow the path of pursuit of others.
Tacha Islam has deliberately outlawed trade and commerce in those trades which are genuinely divisive, or whose profits and losses depend entirely on fate or circumstance or in which the interests and rights of both parties are not specified.
In fact, a study of Islam's rules on business and commerce shows that most of the ways in which people are now becoming millionaires are the ones on which Islam has imposed strict legal restrictions. It is almost impossible to build unlimited wealth if we work within the range of the means of earning money which Islam declares to be legitimate.
