Once the popularity of jihad in the world to the extent that many people misunderstand jihad. They regard jihad with war, but jihad in Islam is not synonymous with war especially with mischief. Islam does not hate the non-Muslims, but why do so many people consider those who commit terror is mujahhid (the jihad). It is a wrong assumption.
The term "Jihad" is also used to fight against the passions, Shaytan, and people who fasiq (those who do evil and terror). The way fight lust is to learn Islam (learn properly), and then practice it and then teach it. The jihad against Shaytan to reject all forms of doubtful and lust are always decorated by Shaytan. Jihad against the infidel by hand, treasure, oral, and liver. The jihad against the people fasiq by hand, oral and heart.
Jihad means to struggle in earnest in the way of Allah with all the capabilities of both the treasure, soul, spoken, like any other. Jihad is primarily intended for the defense of the oppressed.
And what is the matter with you that you fight not in the cause of Allah and of the weak — men, women and children — who say, ‘Our Lord, take us out of this town, whose people are oppressors, and make for us some friend from Thyself, and make for us from Thyself some helper?’ (Quran 4:76)
Historically, Islam never teaches enmity and destruction. Islam only defend themselves if the oppressed and persecuted. So if there are people who deliberately bombed churches, synagogues, mosques (whether Sunni or Shia), they would not believe and practice the Word of God above. Imagine if all the reciprocal destroyed the houses of worship of the other, how we all can worship in peace?
Jihad is a commandment of God in the Qur'an to uphold the rights and defeat falsehood. To protect people, the oppressed from those who oppress zhalim / slaughter.
Terrorism can not be categorized as a Jihad; Jihad in the form of war must be clear which parties were involved in the war, like the war of the Prophet Muhammad who represents Makkah and Madinah against its allies. The reason for the war was mainly triggered by the tyranny of the Quraysh who violate the right to life of the Muslims who were in Makkah (including seizure of property and the expulsion of the Muslims).
War in the name of Islam, but not enforcement follow Sunnah can not be called Jihad. Sunnah to enforce Islam begins preaching nonviolence!, Not in the form of terrorism, move to a safe area and receive missionary apostle, then actualize the Islamic community (Ummah), which aims to uphold God's power on earth.
