Jihad is not one of the five pillars of Islam. The five pillars are Shahada (faith declaration), Salat (prayer), Zakat (charity), Sawm (fasting), and Hajj (pilgrimage). Jihad, which means striving or struggling, is an important concept in Islam but is not one of the pillars.

Jihad, as described in the Quran, refers to a struggle or effort to strive towards self-improvement, to defend one's faith, or to promote justice and peace. It can be both an internal spiritual struggle (greater jihad) and a physical defense of Islam in the face of aggression (lesser jihad). Terrorism, on the other hand, involves the deliberate targeting of innocent civilians, causing fear and harm, which is explicitly condemned in Islam. Jihad promotes peace, while terrorism goes against the principles of Islam by causing harm to innocent people.

There is nothing in Islam religion called Islamism or jihadism. There is Islam and jihad. The difference between them is that Islam is a religion per Qur'an revelation by God to Prophet Muhammad (peace be upon him) through the angel Gabriel (or Jibril). However, jihad is the struggle ; practiced by Muslims and one Muslims; to get life requirements, raise up families, practice good morals and religion teachings as well as struggle to defend lands, homes, families, and religion against military attacks. When Islam interferes with politics it is called political Islam. When jihad is directed ti fulfill political goals it is called political jihad. Refer to related questions below.

Global Jihad means (betraying god in Islam) Even if you're a Muslim and you betrayed god you will get punished by god.

No one can claim that Jihad failed. Jihad means in Arabic struggle. Jihad is a normal practice in our lives irrelevant to gender, race, or face. Every practices Jihad but could be for different reasons as getting better education, better job, a good wife or husband, good position, etc... Refer to question below.

"There is no Al Qaida in neither Bosnia nor Kosovo.

There is a huge difference in mentalities between south Slavs and Arabs."

Yes, there is a huge difference in mentality between the Slavs and Arabs. However, there is not a huge difference in mentality between Bosnian Muslims, many of whom are of Turkish ancestry, and of a radical Muslim orientation. There is also less difference in mentality between the Albanians in Kosovo, the great majority of whom are Muslim. The Albanians seeking independence for Kosovo have the misfortune of being led by many groups of organized criminals (Mafia type ... and into all the same things as the Mafia ... ); these groups sought aid from Al Qaida in the push to kill or otherwise get rid of all Serbs in Kosovo. Also, the great majority of Albanians in Kosovo were resettled there, from Albania, during WWII by Hitler and Mussolini in order to lessen Serbian influence in the area.

Al Qaida saw opportunity for "Jihad" in both Bosnia and Kosovo. If you think 'there is no Al Qaida' involved in either struggle, you are sadly mistaken.

Which now brings the question, why did the U.S. pay Al Qaida in both these places? Because, due to mistaken policies as well as ignorance, the U.S. felt that Serbian Orthodox Christians-unwillingly under a socialist (i.e., 'remodelled' communist) government were its enemies, and saw the opportunity to hopefully cozy up with Islamic regimes, and come out as the 'savior of human rights' by attacking Serbia; the U.S. paid lots of money (it always does-a good employer!) to buy "allies" it thought would further its 'future policies' ... and, as has happened more than countless times in the past, it picked bad "allies," "allies" who came back to bite the hand that fed them ... and, as is usual in these misadventurous debacles, the hand that had fed its allies was probably not totally unworthy of being bitten. One cannot attempt to dictate to the world and get nothing in return but polite and subsevient cooperation ...

Muhammad ibn al Uthaymeen died on 2001-01-05.

Jihad is a tenet of Islam and a religious duty to strive in the way of God. There are two general ways to do this, the Greater Jihad and the Lesser Jihad. The Greater Jihad is an introspective journey to conquer your internal demons and follow the Divine Laws more closely than previously; this kind of jihad should be entirely peaceful. The Lesser Jihad refers to conflicts and confrontations between Muslims and Non-Muslims or other Muslims, which often erupt in war, but can also be performed through non-violent protests, debate, and advocacy.

They were established by Israel as a counterbalance to the PLO.

Meanwhile, back on Earth . . .

Based on the principles of Islamic fundamentalism gaining momentum throughout

the Arab world in the 1980s, Hamas was founded in 1987 (during the First Intifada)

as an offshoot of the Egyptian Muslim Brotherhood. Co-founder Sheik Ahmed Yassin

stated in 1987 and the Hamas Charter affirmed in 1988 that Hamas was founded to

liberate Palestine from Israeli occupation and to establish an Islamic state in the area

that is now Israel, the West Bank, and the Gaza Strip.

The Israelis and the Palestinians are not fighting over the Gaza Strip. There are

presently no Israelis living there and no Israeli military forces stationed there.

The area is presently governed by Hamas, a political/military entity listed by the

US State Department as an international terrorist organization, and with the

explicit, publicly expressed goal of destroying Israel. Weapons and ammunition

are constantly flowing into the area, from Sinai, through tunnels under the

border policed by Egypt, and from time to time, rockets are launched from

inside Gaza and land in civilian neighborhoods in nearby Israeli cities. Also

from time to time, Israel mounts a military operation designed both to take

rocket manufacturing and launching facilities out of operation, and to register

its disapproval of their use. Like, say, the US might do, if, say, rockets launched

from Tijuana were to rain down on residential neighborhoods in San Diego.

Hamas is an Arab Muslim Terrorist and Paramilitary Organization. Hamas operates out of the Gaza Strip and Qatar. (Prior to 2011, Hamas operated out of Syria, but their Anti-Assad position during Arab Spring got them evicted from Syria.) Some particular elements of Hamas Ideology include:

Jihadist Ideology
In terms of politics, Hamas is a Jihadist organization. Jihadism is a political ideology whose goal is to bring a particularly repressive version of the religious tenets of Islam into the daily functioning of a government and its laws. Additionally, it believes that violence in defense of the faith is the preferred way to do this. Jihadism is a political ideology rooted in Islamic religious concepts, but not part of the Islamic religion per se. Hamas argues that its Jihadist struggle is part of the holy Islamic struggle of Jihad and anyone who opposes them is not properly guided (in Islam). Because of the religious sectarian orientations, Hamas identifies itself as avowedly Sunni, but accepts Shiites because of Iranian funding.

Anti-Israel Sentiment
In the Jihadist conception, only Muslims should be in power in the State and any non-Muslim minorities should have a secondary role if they should have one at all, whereas Jews are too "uppity" in having created a state where they are in the dominant position. Second, Israel is situated in territory which used to be governed by Muslims for nearly 1300 years (with a century-long break under the Crusader States). As a result, Israel is considered a usurpation of historical Islamic authority whereas European countries (for example) never had Islamic authority before.

Anti-Semitism (Jew-Hatred)
Hamas is a virulently Jew-hating Organization. Not only do they oppose Israel's very existence, they have references in their charter to the elimination of all Jews throughout the world. While Islam is not inherently Anti-Semitism, its doctrines are easily to meld to an Anti-Semitic world vision and historically have been melded in such ways. Islam has several Anti-Semitic thrusts. In addition to the crucifixion of Jesus the Messiah (which is not deicide in Islam since Jesus is not God in Islamic theology and because Jesus eluded the attempt to crucify him), Muslims have made the argument that Jews are the killers of the Prophets plural, even though Jesus was the only one of the 35 prophets in the Qur'an who Jews attempted to kill (per Islamic teachings). Additionally, Muhammad and the early Muslims had negative political and military relationships with Arabian Jews which led to Anti-Semitism having a greater prominence in the early Islamic tradition. Hamas has endorsed and promoted all of these Anti-Semitic Views.

Terrorism and Attacking Civilians
The most common and identifiable Hamas terrorist action is the suicide bomber who blows himself up to take out some enemies as well as himself, but Hamas has increasingly used missiles and rockets. Most Muslim terrorists wish to inspire fear in their enemies and therefore primarily attack civilians, considering them part of the enemy.

Palestinian Nationalism
Hamas argues that the Palestinians are the indigenous people of the southwest Levant and Hamas is aggrieved that people from abroad would come to the land that their people's parents, grandparents, and great-grandparents had lived on and worked for as long as they could remember. Hamas refuses to help settle Palestinian Refugees and encourages the children and grandchildren of refugees to remember where in current-Israel they came from: the exact village and street. The point is to create an emotional and intractable grievance to push for Palestinians having the right to go back to their homes in contrast to more realistic solutions.

Welfare for Public Support
Since Hamas exists in Palestine, which has a weak internal support structure, it will use its own funds to build schools, parks, hospitals, and other social services in the communities it occupies. It provides goodwill with the local inhabitants and allows them to more effectively spread whatever messages they may wish to say.

Irreverence Towards Democracy
Hamas has actively engaged in elections in Palestine with its own political parties. However, the engagement is a farce, because if the governments formed after the elections were not desirable to Hamas, Hamas has engaged in militant actions to force the national government to capitulate to their desires. As a result of Hamas's discontent there was a Palestinian Civil War in Gaza and the West Bank. Hamas continues to murder Fatah militants and politicos in the Gaza Strip as a method of securing power.

Charter
You can read more about Hamas's beliefs and ideals in the Charter of Hamas, linked here, which explains in Hamas' own words the main points and views of the organization.

Hindu jihad is nothing but struggle, Hindu jihad normally Hindu millants will say to themselves. RSS and sister organization involving in current terrorism in India, Pakistan and Nepal.

This Hindu jihadhis will fight again christian & Muslim conversion, keep bombs in Muslim mosque and christian churches.

eg. - many christian sisters in madhya pradesh was raped and killed by this jihadhis

In the lifetime of Muhammad, when the Muslims started to fight the Meccan idolatres. These events took place on the Arabian Peninsula, mainly around the areas of Mecca and Medina.

Even though Islam emphasizes on being good and doing good as the path to heaven, some misled Muslims believe that killing non-Muslims will get them to heaven.

NO Muslims do not kill to get to heaven if anything that is considered the way to HELL. Only under extreme circumstance like jihad when an enemy will force Muslims into war is killing a person permissible.

Different jihads contributed to state formation in West Africa by grouping similar minded people within a certain territory, which then established boundaries to separate their state from other warring factions.

The first Jihad was proclamed by Muhammad after he traveled from Mecca to Medina.

Those who engage in jihad (apex)

Every concept, or word for a concept, has two meanings: what the user wishes it to mean and what it means to the listener, based on his or her experience. Jihad means "struggle" and some wish to use it to mean "interior effort to reach self-perfection" kind of struggle. Many people however heard it to mean "holy war" based on the number of Muslims who have committed atrocities while claiming they were on jihad (the Arabic word for "jihad-ers" is "mujahideen").

Some Muslims wish "jihad" to mean the latter (i.e., killing people). Others think Western interpretation of this sort is unfair to them.

It's something of a problem to say which version is "correct" without being able to read the speaker's mind. A perfectly analogous situation surrounds the word "crusade": to a Westerner, "crusade" means a dedicated effort to correct something, as in "Crusade against Illiteracy" or "Crusade for Clean Water." To Muslims, however, the term only means "military action against Muslims."

Assuming that you are referring exclusively to violent Lesser Jihad, e.g. the Islamic Holy War, as opposed to Greater Jihad (self-reflection and self-improvement) or peaceful Lesser Jihad (advocacy and protesting), the numbers are unclear. A lot comes down on how you phrase the question, whether you are talking about reality or theory, whether you are talking about monetary support or simply vocal allegiance, which Jihadist organization you are talking about, etc. However, we are talking about a significant minority, between 15-40% of Muslims. It is worth noting that less than 1% are actually engaged in violent Lesser Jihad.
