One of the stories  concerning the environment is the instruction by `Abu Bakr,` the first Caliph (Khalif) of Islam to his armies. In addition to telling them not to harm women, children and the infirm, he ordered them not to harm animals, destroy crops or cut down trees.
There were two elements present in this decree: the first, to establish justice even as the Muslim armies fought, and **the second, to recognize the value of nature.**

The Prophet instructed that any Muslim who plants a crop that feeds another person,
animal or bird, will receive a reward in paradise. 

> The Prophet (sallallahu 'alaihi wa sallam) said: "When doomsday comes,
> if someone has a palm shoot in his hands, he should plant it."
