The term "jihad" has multiple meanings and interpretations, depending on the context in which it is used. In general, it refers to the obligation incumbent on all Muslims, individuals and the community, to follow and realize God’s will: to lead a virtuous life and to extend the Islamic community through preaching, education, example, writing, etc. . Jihad also includes the right, indeed the obligation, to defend Islam and the community from aggression. The peaceful sense of "efforts towards the moral uplift of society or towards the spread of Islam" can be known as "jihad of the tongue" or "jihad of the pen", as opposed to "jihad of the sword". The term "jihad" has been used by resistance, liberation, and terrorist movements alike to legitimate their cause and motivate their followers. It is important to note that Islam does not condone acts of terror, and war is only legitimized when there are no peaceful alternatives and the motivation is pure, with good intention to combat injustice. Throughout Islamic history, wars against non-Muslims, even when motivated by political and secular concerns, were termed jihads to grant them religious legitimacy.
