Like other faiths, Islam permits fighting as a means of self-defense or in defense of religion, or on the part of those who have been forcibly expelled from their homes.
Treatises and dissertation have been written detailing the rules of engagement in war in which scholars have laid down strict rules of combat, which include prohibitions against harming civilians including women and children, and against destroying crops, trees, livestock and polluting of drinking water.
One of the most important aspects of a Muslim's life is to have high moral standards. Since the beginning of Islam, Prophet Muhammad 
was mainly concerned with teaching and disciplining Muslims to have the best manners and personal characteristics. His personal life and behaviour were reflective of his teachings, which were revealed to him by Allaah. In the Noble Quran, Allaah describes Prophet Muhammad saying (what means): “And indeed, you are of a great moral character.” [Quran, 68:4]
The Shi‘a and Sunni schools of thought form the two wings of the Islamic nation that allow it to fly and carry out its lofty objectives. A great Muslim scholar once said, “Those who attempt to cause division between the Shi‘a and Sunni are neither Shi‘a nor Sunni.” Written under this premise, the book in hand should clarify some common questions and inquiries about the philosophy and practice of Shi‘a Islam. The Shi‘a and Sunni schools of thought differ primarily in jurisprudence and have far more similarities than differences. Every school of thought in Islam must be respected because they all can lead people to salvation.
