Jihad is an Arabic word which derives from the three-letter root j-h-d, and means "to exert oneself" or "to strive." Other meanings include endeavor, strain, effort, diligence, struggle. Usually understood in terms of personal betterment, jihad may also mean fighting to defend one's (or another's) life, property, and faith. Because jihad is a highly nuanced concept, it should not be understood to mean "holy war," a common misrepresentation.
It is an Arabic word the root of which is Jahada, which means to strive for a better way of life. The nouns are Juhd, Mujahid, Jihad, and Ijtihad. The other meanings are: endeavor, strain, exertion, effort, diligence, fighting to defend one's life, land, and religion.
Jihad should not be confused with Holy War; the latter does not exist in Islam nor will Islam allow its followers to be involved in a Holy War. The latter refers to the Holy War of the Crusaders.
Jihad is not a war to force the faith on others, as many people think of it. It should never be interpreted as a way of compulsion of the belief on others, since there is an explicit verse in the Qur'an that says:There is no compulsion in religionAl-Qur'an: Al-Baqarah (2:256).
Jihad is not a defensive war only, but a war against any unjust regime. If such a regime exists, a war is to be waged against the leaders, but not against the people of that country. People should be freed from the unjust regimes and influences so that they can freely choose to believe in Allah.
Not only in peace but also in war Islam prohibits terrorism, kidnapping, and hijacking, when carried against civilians. Whoever commits such violations is considered a murderer in Islam, and is to be punished by the Islamic state. during wars, Islam prohibits Muslim soldiers from harming civilians, women, children, elderly, and the religious men like priests and rabies. It also prohibits cutting down trees and destroying civilian constructions.
