The Hadith make Jihad in the name of Allah both an obligation and path to salvation.

In Bukhari's Hadith, there are 'only' 300 or so verses commanding Jihad. This proves that Islam has nothing to do with violence, war, plunder, rape and murder. The Hadiths are the corollary works to the Koran; and include all aspects of the life of the totalitarian Muhammad, as he established his fascist 'us versus them', cult. Jihad means to wage war to spread Islam. This is the primary purpose of Muhammad's cult. A secondary meaning and inferior to the first, is that Jihad means striving to overcome the natural tendency to do wrong or evil; or to 'cleanse' your own self.

It is clear however that the Koran and Hadiths demand first and foremost the physical Jihad, or the fighting against Unbelievers. This is only common-sense. In Muhammad's world-view the spiritual struggle comes after victory against the untermensch Unbelievers. Indeed the Koran and Hadiths make it clear that Islam must conquer the world. This is an obvious declaration of war.

Bukhari Hadith: “Narrated Anas bin Malik: The Prophet said, "A single endeavor (of fighting) in Allah's Cause in the forenoon or in the afternoon is better than the world and whatever is in it." 

 Narrated Ibn 'Abbas: On the day of the Conquest (of Mecca) the Prophet said, "There is no emigration after the Conquest but Jihad and intentions. When you are called (by the Muslim ruler) for fighting, go forth immediately." (See Hadith No. 42)  

Narrated 'Abdullah bin Abi Aufa: Allah's Apostle said, "Know that Paradise is under the shades of swords." 

 Narrated Jundab bin Sufyan: In one of the holy Battles a finger of Allah's Apostle (got wounded and) bled. He said, "You are just a finger that bled, and what you got is in Allah's Cause." 

 Narrated Al-Bara: A man whose face was covered with an iron mask (i.e. clad in armor) came to the Prophet and said, "O Allah's Apostle! Shall I fight or embrace Islam first? "The Prophet said, "Embrace Islam first and then fight." So he embraced Islam, and was martyred. Allah's Apostle said, A Little work, but a great reward. "(He did very little (after embracing Islam), but he will be rewarded in abundance)."  

Narrated Abu Huraira: Allah's Apostle said, "Allah welcomes two men with a smile; one of whom kills the other and both of them enter Paradise. One fights in Allah's Cause and gets killed. Later on Allah forgives the 'killer who also get martyred (In Allah's Cause)."  

These are just some examples where Muhammad, who was much admired by Hitler, ordered his men to fight and kill. Even if you were a brigand and murderer, once you join the Allah-cult, or cult of Muhammad, you will be forgiven all past transgressions, as long as you fight for Allah. The key is that you must physically fight and kill or attempt to kill Unbelievers in the name of Allah. Jihad is an integral to Islam as racism and evolution were to Nazism.
