There are so many quotations from Imam Sadiq (peace be upon him) about how to deal in the Islamic society. As an Example, he said that the Muslim man should profit in the right amount, not more than that. His saying is that your profit should be accompanied with compassion and consideration. (al-Hayat, vol. 2, p. 236).
Imam Sadiq's attitude is such that many people who see if the supply of a product is less than its demand, they try to make more money and profit in their pocket with the hoarding of Goods and putting pressure on people and they only consider their own personal interests.
