Caring for trees and greening the environment is significant for the protection of five major principles and objectives (religion, soul, intellect, generation and assets (of the Islamic Shari’ah. Planting trees has a clear effect on human physical and mental health. On the other hand, planting trees plays a significant role in the development of the economy, through which many agricultural products are obtained. Hence, for this, the rules and regulations that have been made at the national and international levels ought to be fully implemented. Generally, cutting down of trees and deforestation should be prohibited and criminals should be punished. There is an inseparable relationship between trees, shrubs, the natural environment and humans that has a direct connection with the souls and spirits of humans. The human soul feels comfortable and peaceful in the green environment. If you look at the nature of human, Allah subhanahu wa ta’ala (SWT) created Adam Alaihis Salam (peace be upon him) and placed him in Paradise. He lived there and benefited from the gardens of Paradise. As Allah subhanahu wa ta’ala (SWT) has mentioned in the Holy Qur'an, human is naturally created in such a way that they feel at peace with the green environment. Therefore, a green environment should be provided and every possible measure should be applied when it is destroyed.
