Da'i in the context of "Allah"

The Fatimid Caliphate (/ˈfætɪmɪd/; Arabic: الخلافة الفاطمیّة, romanized: al-Khilāfa al-Fāṭimiyya), also known as the Fatimid Empire, was a caliphate extant from the tenth to the twelfth centuries CE under the rule of the Fatimids, an Isma'ili Shi'a dynasty. Spanning a large area of North Africa and West Asia, it ranged from the western Mediterranean in the west to the Red Sea in the east. The Fatimids traced their ancestry to the Islamic prophet Muhammad's daughter Fatima and her husband Ali, the first Shi'a imam. The Fatimids were acknowledged as the rightful imams by different Isma'ili communities as well as by denominations in many other Muslim lands and adjacent regions. Originating during the Abbasid Caliphate, the Fatimids initially conquered Ifriqiya (roughly present-day Tunisia and north-eastern Algeria). They extended their rule across the Mediterranean coast and ultimately made Egypt the center of the caliphate. At its height, the caliphate included—in addition to Egypt—varying areas of the Maghreb, Sicily, the Levant, and the Hejaz.

Between 902 and 909, the foundation of the Fatimid state was realized under the leadership of da'i (missionary) Abu Abdallah, whose conquest of Aghlabid Ifriqiya with the help of Kutama forces paved the way for the establishment of the Caliphate. After the conquest, Abdallah al-Mahdi Billah was retrieved from Sijilmasa and then accepted as the Imam of the movement, becoming the first Caliph and founder of the dynasty in 909. In 921, the city of al-Mahdiyya was established as the capital. In 948, they shifted their capital to al-Mansuriyya, near Kairouan. In 969, during the reign of al-Mu'izz, they conquered Egypt, and in 973, the caliphate was moved to the newly founded Fatimid capital of Cairo. Egypt became the political, cultural, and religious centre of the empire and it developed a new and "indigenous Arabic culture". After its initial conquests, the caliphate often allowed a degree of religious tolerance towards non-Shi'a sects of Islam, as well as to Jews and Christians. However, its leaders made little headway in persuading the Egyptian population to adopt its religious beliefs.

Abd Allah ibn Abi Quhafa (Arabic: عَبْدُ اللهِ بْنُ أَبِي قُحَافَةَ, romanized: ʿAbd Allāh ibn ʾAbī Quḥāfa) (c. 573 – 23 August 634), better known by his kunya Abu Bakr, was a senior companion, the closest friend, and father-in-law of Muhammad, the Islamic prophet. He served as the first caliph of the Rashidun Caliphate, ruling from 632 until his death in 634. Abu Bakr was granted the honorific title al-Ṣiddīq (lit. the Veracious) by Muhammad, a designation that continues to be used by Sunni Muslims to this day.

Born to Abu Quhafa and Umm al-Khayr of the Banu Taym, Abu Bakr was among the earliest converts to Islam and propagated dawah to the Mushrikites. He was considered the first Muslim missionary, as several companions of Muhammad converted through Abu Bakr. He accompanied Muhammad on his migration to Medina and became one of his bodyguards. Abu Bakr participated in all of Muhammad's campaigns and served as the first amir al-hajj in 631. In the absence of Muhammad, Abu Bakr led the prayers.

Abu Abdallah al-Husayn ibn Ahmad ibn Muhammad ibn Zakariyya, better known as Abu Abdallah al-Shi'i (Arabic: ابو عبد الله الشيعي, romanized: Abū ʿAbd Allāh ash-Shīʿī), was an Isma'ili missionary (dāʿī) active in Yemen and North Africa. He was successful in converting and unifying a large part of the Kutama Berber tribe, leading them on the conquest of Ifriqiya from 902 to 909 and the overthrowing of the Aghlabid dynasty. This ultimately led to the establishment of the Fatimid Caliphate in Ifriqiya under the Imam–caliph Abdullah al-Mahdi Billah. However, Abdullah al-Mahdi Billah quickly fell out with Abu Abdallah and had Abu Abdallah executed on 18 February 911.

Daʿwah (Arabic: دعوة, Arabic: [ˈdæʕwæ], "invitation", also spelt dâvah, daawa, dawah, daawah or dakwah) is the act of inviting people to Islam. The plural is daʿwāt (دَعْوات) or daʿawāt (دَعَوات). Preachers who engage in dawah are known as da'i.

Abu al-Husayn Ahmad ibn Abd Allah ibn Muhammad ibn Isma'il (Arabic: أَبُو ٱلْحُسَيْن أَحْمَد ٱبْن عَبْد ٱللَّٰه ٱبْن مُحَمَّد ٱبْن إسْماعِيل, romanized: Abū al-Ḥusayn Aḥmad ibn ʿAbd Allāh ibn Muḥammad ibn Ismāʿīl; c. 790–840), commonly known as Muhammad al-Taqi (Arabic: مُحَمَّد ٱلْتَقِيّ, romanized: Muḥammad al-Taqī, lit. 'Muhammad the Pious'), was a descendant of the Islamic prophet Muhammad and the ninth of the Isma'ili Imams, succeeding his father, Ahmad al-Wafi (d. 828). Like his father, he lived primarily in Salamiyah, and Abd Allah ibn Maymun al-Qaddah, the chief missionary (da'i), continued to serve as the hijab (lit. 'cover') for him. Known by the title Ṣāḥib al-Rasāʾil (lit. 'lord of the epistles'), al-Taqi is said to have prepared with his followers an encyclopedic text called the Encyclopedia of the Brethren of Purity (Rasāʾil Ikhwān al-Ṣafā). He died in 840 in Salamiyah and was succeeded by his son al-Husayn.

With the death of Ja'far al-Sadiq in 148/765, Isma'il (d. 158/775) and Muhammad (d. 197/813), the gravity of persecutions of the Abbasids had considerably increased. The Isma'ili Imams were impelled to thicken their hiding, therefore, the first dawr al-satr came into force from 197/813 to 268/882, wherein the Imams were known as al-a'imma al-masturin (lit. 'the concealed Imams'). The concealment ended with the establishment of the Fatimid Caliphate (r. 909–1171).

The Fatimid Caliphate (/ˈfætɪmɪd/; Arabic: الخلافة الفاطمیّة, romanized: al-Khilāfa al-Fāṭimiyya), also known as the Fatimid Empire, was a caliphate extant from the tenth to the twelfth centuries CE under the rule of the Fatimids, an Isma'ili Shi'a dynasty.
