The true Jihad, is the Jihad against the Self.
http://www.uga.edu/islam/sufismstruggle.htmlIn this regard, the struggle with one's own nafs has been called the greater struggle or greater "holy war" (al-jihad al-akbar) in contrast to the lesser struggle (al-jihad al-asghar), which is against injustice and oppressors in this world. The concept derives from the popular hadith of the Prophet, in which he said to Muslims returning from a battle, "You have returned from the lesser struggle to the greater struggle." And he was asked, "What is the greater struggle?" He answered, "The struggle against one's self (nafs), which is between the two sides of your body." Needless to say, in Sufism these two struggles are mutually reinforcing and occur simultaneously. In particular, the practice of "engaged surrender" in the "greater" struggle with one's own nafs diminishes certain obstacles in the consciousness of the Sufi, obstacles that--if not stuggled against--will hinder the Sufi's capacity to engage in the "lesser" struggle in their life in the world.
