This is Islam in its own words

"Since the objective of Islam is a decisive declaration of man's freedom, not merely on the philosophical plane but also in the actual life, it must employ jihad. It is immaterial whether the homeland of Islam--in the true Islamic sense, dar al-Islam--is in a condition of peace or whether it is threatened by its neighbors. When Islam calls for peace, its objective is not a superficial peace requiring only that part of the earth where the followers of Islam are residing remain secure. The peace of Islam means that din [the law of society] be purified for Allah, that all people should obey Allah alone, and every system that permits some people to rule over others be abolished."

Sayyid Qutb, Milestones, p.51. This is Islam in its own words.
