Since Islam is the last religion revealed by Allah, it possesses some elements that make it unique. One of these is its relevance for human beings regardless of place and time.

This means that Islam - submission to God - is a comprehensive institution which includes all the guidelines necessary for all aspects of life. Therefore, the best way to understand Islam is to look at it as more than a religion - as a complete way of life. In other words, it is a system which regulates every aspect of life, dealing with all issues - social, economic, educational, judicial, health, and even military. Thus, it is suitable for all human beings and for all times, since it is the final religion. Islamic law aims to achieve five goals for human beings in life: protecting the religion, protecting one's self, protecting one's possessions, protecting one's mind, and protecting one's offspring.

Therefore, God (Allah) decided on two main domains of law:

To show how Islam cares for the environment, one can cite the many laws that protect the environment. About fourteen hundred years ago. Prophet Muhammad (pbuh) said:

"The world is green and beautiful, and Allah has appointed you as His stewards over it. He sees how you acquit yourselves."

Muhammad showed how important plants and trees are by saying: "Whoever plants a tree and looks after it with care until it matures and becomes productive will be rewarded in the Hereafter." Even in the territory of an enemy, Islam's care for plants, animals, and trees is profound. Abu Bakr, the first Caliph, or successor, to Muhammad (pbuh), instructed his troops that he was sending into battle not to cut down any trees or kill any animals except for food.

These are but a few examples of how Islam remains relevant in the modern world.
