Rashidun armyThe Rashidun army (جيش الراشدين) was the core of the Rashidun Caliphate's armed forces during the early Muslim conquests in the 7th century. The army is reported to have maintained a high level of discipline, strategic prowess and organization, granting them successive victories in their various campaigns. In its time, the Rashidun army was a very powerful and effective force. The three most successful generals of the army were Khalid ibn al-Walid, who conquered Persian Mesopotamia and the Roman Levant, Abu Ubaidah ibn al-Jarrah, who also conquered parts of the Roman Levant, and Amr ibn al-As, who conquered Roman Egypt.
Suicide attackA suicide attack is any violent attack, usually entailing attackers detonating an explosive, where any attackers have accepted their own death as a direct result of the attacking method used. Suicide attacks have occurred throughout history, often as part of a military campaign (as with the Japanese kamikaze pilots of 1944–1945 during World War II), and more recently as part of Islamic terrorist campaigns (such as the September 11 attacks in 2001).
Banu QurayzaThe Banu Qurayza (بنو قريظة; alternate spellings include Quraiza, Qurayzah, Quraytha, and the archaic Koreiza) were a Jewish tribe which lived in northern Arabia, at the oasis of Medina (previously known as Yathrib). They were one of the three major Jewish tribes of the city, along with the Banu Qaynuqa and Banu Nadir, before their elimination by the Islamic prophet Muhammad. Jewish tribes reportedly arrived in Hijaz in the wake of the Jewish-Roman wars and introduced agriculture, putting them in a culturally, economically and politically dominant position.
Islamic StateThe Islamic State (IS), also known as the Islamic State of Iraq and the Levant (ISIL; ˈaɪsᵻl), Islamic State of Iraq and Syria (ISIS; ˈaɪsᵻs), and by its Arabic acronym Da'ish or Daesh (داعش, Dāʿish, ˈdaːʕɪʃ), is a transnational militant Islamist terrorist group and former unrecognized quasi-state that follows the Salafi jihadist branch of Sunni Islam. It was founded by Abu Musab al-Zarqawi in 1999 and gained global prominence in 2014, when it captured a large amount of Iraqi territory, and took advantage of the civil war in Syria to take control of chunks of territory in Eastern Syria.
IslamIslam (ˈɪslɑːm; ۘالِإسْلَام, al-ʾIslām ʔɪsˈlæːm, ) is an Abrahamic monotheistic religion centered on the Quran and the teachings of Muhammad. Adherents of Islam, called Muslims, number approximately 2 billion globally and are the world's second-largest religious population after Christians. Muslims believe that Islam is the complete and universal version of a primordial faith that was revealed many times through earlier prophets such as Adam (believed to be the first man), Ibrahim, Moses, and Isa (Jesus), among others.
Islamic terrorismIslamic terrorism (also known as Islamist terrorism or radical Islamic terrorism) refers to terrorist acts with religious motivations carried out by fundamentalist militant Islamists and Islamic extremists. Incidents and fatalities from Islamic terrorism have been concentrated in eight Muslim-majority countries (Afghanistan, Egypt, Iraq, Libya, Nigeria, Pakistan, Somalia, and Syria), while four Islamic extremist groups (Islamic State, Boko Haram, the Taliban, and al-Qaeda) were responsible for 74% of all deaths from terrorism in 2015.
JihadJihad (dʒɪˈhɑːd; jihād dʒiˈhaːd) is an Arabic word which literally means "striving" or "struggling", especially with a praiseworthy aim. In an Islamic context, it can refer to almost any effort to make personal and social life conform with God's guidance, such as struggle against one's evil inclinations, proselytizing, or efforts toward the moral betterment of the Muslim community (Ummah), though it is most frequently associated with war.
