Do productive works
Imam Sadegh (a.s): 'Cultivate and plant tree. By god, people have not done any action more lawful and pure than this.'
Man"s life is based on productive works, including agriculture, and different businesses, even most of industries would not be meaningful without agriculture because they gain their raw materials from it. In addition, defraudation and trickery is not possible in agriculture as the other things. Because its basis is natural factors and means and its profits is merely the result of sincere efforts of men. On this account, cultivation and planting tree is called the most pure and pleasant work in the above tradition.
