According to the Quran and Sunnah, a Muslim has to discharge his moral responsibility not only to his parents, relatives and neighbors but to the entire mankind, animals and trees and plants. For example, hunting of birds and animals for the sake of game is not permitted. Similarly, cutting trees and plants which yield fruit is forbidden unless there is a very pressing need for it.
Thus, on the basic moral characteristics, Islam builds a higher system of morality by virtue of which mankind can realize its greatest potential. Islam purifies the soul from self-seeking egotism, tyranny, wantonness and indiscipline. It creates God-conscious men, devoted to their ideals, possessed of piety, abstinence and discipline and uncompromising with falsehood, It induces feelings of moral responsibility and fosters the capacity for self-control. Islam generates kindness, generosity, mercy, sympathy, peace, disinterested goodwill, scrupulous fairness and truthfulness towards all creation in all situations. It nourishes noble qualities from which only good may be expected.
