Imam Al-Sadiq (A.S)
In the time of our 6th Imam, Imam Al-Sadiq (A.S) there was once a wheat shortage in Medina. As a result the people of Medina were buying as much wheat as they could afford.
There were some people who were quite poor and could only afford to buy enough wheat for that day.
These people had to pay a little bit more for the wheat each day because there was less and less wheat available.
Imam Sadiq (A.S) asked his servant how much wheat they had in the house. The servant replied that they had enough to last them for several months.
Imam (A.S) then told the servant to take the wheat to the market and sell it all to the people.
The servant argued that if he did this then they probably would not be able to buy all the wheat back and also they would have to pay a lot more for it.
Imam (A.S) told him that it did not matter. He told him that after he had sold all the wheat he should only buy enough wheat for each day.
Imam (A.S) also told his servant that from then on the bread in his house should be made from ½ wheat and ½ barley.
Moral: Imam Al-Sadiq (A.S) did this because he did not want to live in a better manner while so many people were hungry. Islam does not allow hoarding.
