Spread of IslamThe spread of Islam spans about 1,400 years. Muslim conquests following Muhammad's death led to the creation of the caliphates, occupying a vast geographical area; conversion to Islam was boosted by Arab Muslim forces conquering vast territories and building imperial structures over time. Most of the significant expansion occurred during the reign of the Rashidun from 632 to 661 CE, which was the reign of the first four successors of Muhammad.
MissionaryA missionary is a member of a religious group which is sent into an area in order to promote its faith or provide services to people, such as education, literacy, social justice, health care, and economic development. In the Latin translation of the Bible, Jesus Christ says the word when he sends the disciples into areas and commands them to preach the gospel in his name. The term is most commonly used in reference to Christian missions, but it can also be used in reference to any creed or ideology.
Salafi movementThe Salafi movement or Salafism (سلفیة) is a revival movement within Sunni Islam. The movement was formed as a socio-religious resistance to European imperialism during the late 19th century and has remained influential in the Islamic World for over a century. The name "Salafiyya" refers to advocacy of a return to the traditions of the "pious predecessors" (salaf), the first three generations of Muslims (the Islamic prophet Muhammad and his companions, the Sahabah, then the Tabi'in, and the third generation, the Taba al-Tabi'in), who are believed to exemplify the pure form of Islam.
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.
WahhabismWahhabism (ٱلْوَهَّابِيَةُ) is a reformist movement within Sunni Islam, based on the teachings of 18th century Hanbali cleric Muhammad ibn 'Abd al-Wahhab (1703–1792) The term "Wahhabism" is primarily an exonym; it was not used by Ibn 'Abd al-Wahhab himself or adherents to the movement, who typically prefer to be called "Salafi" (a term also used by followers of other Islamic reform movements). The movement's early followers referred to themselves as Muwahhidun (الموحدون) derived from the term Tawhid (the oneness of God).
Isma'ilismIsma'ilism (al-ʾIsmāʿīlīyah) is a branch or sub-sect of Shia Islam. The Isma'ili (ˌɪsmeɪˈɪli) get their name from their acceptance of Imam Isma'il ibn Jafar as the appointed spiritual successor (imām) to Ja'far al-Sadiq, wherein they differ from the Twelver Shia, who accept Musa al-Kadhim, the younger brother of Isma'il, as the true Imām. After the death of Muhammad ibn Isma'il in the 8th century CE, the teachings of Ismailism further transformed into the belief system as it is known today, with an explicit concentration on the deeper, esoteric meaning (batin) of the Islamic religion.
