Isma'il of Sennar
Isma'il( 1736–1776) was the ruler of the Kingdom of Sennar( 1768 – 1776).
He was the son of king Badi IV, and brother of his predecessor Nasir.
The Scottish traveller James Bruce was his unwilling guest from 1 May to 5 September 1772, and acted as a physician to Isma'il's three wives.
Bruce left this portrait of Isma'il:
Bruce summarized Isma'il's political position at the time of his visit as follows, based on conversations with the Royal Executioner, Ahmed Sid el- Koum:
Muhammad ibn Isma'il
Muhammad ibn Ismāʿīl alias Maymūn Al- Qaddāḥ was the son of Isma'il ibn Jafar; he was an Ismāʿīlī Imam.
The majority of Ismāʿīlī follow his descendants through his son Wafi Ahmad( Abdullah ibn Mohammad).
His descendants further founded the Fatimid Empire, also called the Nizari and Mustaali.
Al-Husayn ibn Isma'il al-Mus'abi
Al- Husayn ibn Isma'il ibn Ibrahim ibn Mus'ab( died November 886) was a ninth century army commander in the service of the Abbasid Caliphate.
He was particularly active during the period known as the Anarchy at Samarra( 861–870).
Isma'il ibn Ja'far
Ismāʿīl ibn Jaʿfar al-Mubārak (c. born: 719 AD, Medina - died circa 762 AD, Medina)
was the eldest son of Imam Ja'far al-Sadiq.
He is also known as Isma'il Al-Ãraj ibn Ja'far
(اسماعيل الاعرج ابن جعفر الصادق).
Following Ja'far's death, the Shia community split between those who believed the Imamate was passed to Musa ibn Ja'far, who would become the Twelver Shia, and those who believed that the Imamate passed to Isma'il ibn Ja'far, who would become the Isma'ili branch named after Isma'il.
Ibn 'Ulayya
Abu Bishr Isma'il ibn Ibrahim ibn Muqsim, commonly known as Ibn' Ulayya, was a hadith scholar, faqih and a mufti from Basra.
Nur Felek Qadin
Nur Felek Qadin( died 15 August 1916), was a consort of Isma'il Pasha of Egypt.
Abdullah al-Aftah
Abdullah al- Aftah ibn Ja'far al- Sadiq( d. 766 CE/ 149 A.H.) was the eldest surviving son of Ja'far al- Sadiq( after al- Sadiq ’s death) and the full- brother of Isma'il ibn Jafar.
Abdullah ’s title al- Aftah derives from the Arabic words aftah al- ra ’s( broad- headed) or aftah al- rijlayn( broad- footed) used to describe his appearance.
Ja'far al-Sadiq
Jaʿfar ibn Muḥammad aṣ-Ṣādiq (700 or 702–765 CE), commonly known as Ja'far al-Ṣādiq or simply as-Sadiq (The Truthful), was an 8th-century Muslim scholar and scientist.
He is considered as an Imam and founder of the Ja'fari school of jurisprudence by Twelver and Isma'ili Shi’as, and a major figure in the Hanafi and Maliki schools of Sunni jurisprudence.
He was a descendant of the Caliph Ali and Fatimah bint Muhammad on the side of his father, Muhammad al-Baqir, and of Muhammad ibn Abu Bakr on the maternal side of his family, Umm Farwah bint al-Qasim.
Muhammad ibn Abi Bakr was raised by Ali, but was not his son.
Ali used to say: "Muhammad Ibn Abu Bakr is my son but from Abu Bakr's lineage".
Al-Sadiq is the 6th Imam for Twelvers, is recognized by the majority of the Shi’a as an Imam, and is revered in Sunni Islam as a transmitter of hadiths, therefore a prominent jurist, and a mystic to Sufis.
Despite his wide-ranging attributions in a number religious disciplines, no works penned by Ja'far himself remain extant.
Al-Sadiq was born in either 700 or 702 CE.
He inherited the position of imam from his father in his mid-thirties.
As a Shi’a Imam, al-Sadiq stayed out of the political conflicts that embroiled the region, evading the many requests for support that he received from rebels.
He was the victim of some harassment by the Abbasid caliphs, and was eventually, according to Shi’a Muslims, poisoned at the orders of the Caliph Al-Mansur.
In addition to his connection with Sunni schools of Sunni jurisprudence, he was a significant figure in the formulation of Shia doctrine.
The traditions recorded from al-Sadiq are said to be more numerous than all hadiths recorded from all other Shia imams combined.
As the founder of Ja'fari jurisprudence, al-Sadiq also elaborated the doctrine of "Nass" (divinely inspired designation of each imam by the previous imam), and "Ismah" (the infallibility of the imams), as well as that of Taqiyyah.
The question of succession after al-Sadiq's death was the cause of division among Shi’a who considered his eldest son, Isma'il (who had reportedly died before his father) to be the next Imam, and those who believed his third son Musa al-Kadhim was the imam.
The first group became known as the Ismailis and the second, larger, group was named Ja'fari or the Twelvers.
Raghib Pasha
Isma'il ibn Ahmad ibn Hassan bani Yani, known simply as Isma'il Ragheb Pasha( 1819 – 1884), was a Greek Ottoman politician who served as Prime Minister of Egypt and held several other high- ranking government positions.
Isma'il Ragheb was of Greek ancestry and was born in Greece on 18 August 1819 on either the island of Chios following the great massacre or Candia, Crete.
After being kidnapped to Anatolia he was brought to Egypt as a slave by Ibrahim Pasha in 1830 and was converted to Islam.
Immediately following his arrival, he studied at" al- Maktab al- Amiri" and obtained his advanced degree in 1834.
He was fluent in Greek and was elevated to the rank of First Lieutenant by Egypt's viceroy Muhammad Ali Pasha.
In 1836, he became head of the Accounting and Revenue Agencies.
He was promoted to the rank of" bikbashi"( Lieutenant Colonel) in 1840, then" kaymakam"( Colonel) in 1844, and finally" amiralay"( Brigadier General) in 1846.
He held the positions of Minister of Finance( 1858 – 1860), then Minister of War( 1860 – 1861).
He became Inspector for the Maritime Provinces in 1862, and later Assistant to viceroy Isma'il Pasha( 1863 – 1865).
He was granted the title of" beylerbey" and then appointed President of the Privy council in 1868.
He was appointed President of the Chamber of Deputies( 1866 – 1867), then Minister of Interior in 1867, then Minister of Agriculture and Trade in 1875.
He again held the Finance portfolio in Muhammad Sharif Pasha's first government( 1879).
After the fall of Mahmoud Sami el- Baroudi's government, Isma'il Ragheb became Prime Minister of Egypt in 1882.
Although his government was short- lived( it lasted from 17 June to 21 August only), it was the only one to present concrete programs.
His achievements include the modernisation of the budget through the inventory of revenues and expenses, the Law on Salaries, and the" La'eha Sa'ideyya" as well as several agricultural laws.
Isma'il Ragheb died in 1884.
