ALA (دعوة, ˈdæʕwæh, "invitation", also spelt dâvah, daawa, dawah, daawah or dakwah) is the act of converting people to Islam. The plural is daʿwāt (دَعْوات) or daʿawāt (دَعَوات).
For certain groups within Islam like the Salafis and Jamaat-e-Islami, daʿwah is also considered a political activity. For these groups, the aim of daʿwah outreach is also to engineer a reversal of what they perceive as the decline of Islam in the modern era, through the systematic propagation of Islamist ideology and ultimately enable the establishment of an Islamic state.
Daʿwah ˈdæʕwæh literally means "issuing a summons" or "making an invitation". Grammatically, the word represents a gerund of a verb with the triconsonantal root d-ʕ-w (د-ع-و) meaning variously "to summon" or "to invite". A Muslim who practices daʿwah, either as a religious worker or in a volunteer community effort, is called a ALA (داعي, plural ALA دعاة dʊˈʕæː).
A dāʿī, is a person who invites people to understand and accept Islam through dialogue and other techniques, may be regarded as a missionary inviting people to the faith, prayer and manner of Islamic life.
The term daʿwah has other senses in the Qur'an. In sura (chapter) 30:25, for example, it denotes the call to the dead to rise on the Day of Judgment. When used in the Qur'an, it generally refers to Allah's invitation to live according to his will. Thus, when used in the first centuries of Islam, it usually referred to that message and was sometimes used interchangeably with sharī‘a and dīn.
Daʿwah is also described as the duty to "actively encourage fellow Muslims in the pursuance of greater piety in all aspects of their lives", a definition which has become central to contemporary Islamic thought.
List of expeditions of Muhammad
During the Expedition of Al Raji in 625, Muhammad sent some men as missionaries to various different tribes. Some men came to Muhammad and requested that Muhammad send instructors to teach them Islam, but the men were bribed by the two tribes of Khuzaymah, who wanted revenge for the assassination of Khalid bin Sufyan (Chief of the Banu Lahyan tribe) by Muhammad's followers.
