Muhammad ibn Ja'far
Muhammad ibn Ja'far( Arabic: محمد بن جعفر) was a companion and relative of the Islamic prophet Muhammad.
He was the son of Muhammad's cousin, Ja'far ibn Abu Talib, and of Asma bint Umais.
His uncle Ali particularly wished that his daughters should marry Ja'far's sons.
In due course, Muhammad ibn Ja'far did marry Ali's daughter Umm Kulthum, who was the widow of his brother Awn.
They had no children.
Khawlah bint Ja'far
Khawlah bint Ja'far al- Hanafiyyah/( Umm e Muhammad) was one of the wives of the fourth Muslim Caliph Ali ibn Abi Talib.
Ja'far ibn Muhammad al-Hasani
Ja'far ibn Muhammad ibn Husayn al- Hasani was Sharif of Mecca from the late 960s to the early 970s, and the first Emir belonging to the Musawid dynasty.
He was a Hasanid, descendant of the ninth generation from Hasan ibn Ali.
According to Ibn Khaldun, Ja'far came from Medina and conquered Mecca.
He ordered the" khutbah" in the name of the Fatimid caliph al- Mu'izz after the latter conquered Egypt in 969.
Although the date Ja'far conquered Mecca is not known, Ibn Hazm writes that it was during the reign of the Ikhshidids in Egypt.
Al- Fasi narrows it down to the years 356-358 AH( 967 -969), since Ikhshidid influence in the Hejaz waned after the death of Abu al- Misk Kafur.
However, he does acknowledge that this is contradicted by some chronicles which indicate that Ja'far had Kafur's name pronounced in the khutbah.
The sources provide different dates for the year in which Ja'far captured Mecca: the years 967, 968, 969, and the entire period 951–961 are mentioned.
Ja'far founded a long line of Hasanid Sharifs of Mecca, which lasted until their overthrow by the Saudis in 1924.
Ja'afar's line, the Ja'farid dynasty, ended with Shukr ibn Abi'l- Futuh in 1061.
Medina, on the other hand, was frequently controlled by the Husaynids.
Harun al-Rashid
Harun al-Rashid ("Hārūn Ar-RašīdAaron the Orthodox" or "Aaron the Rightly-Guided", 17 March 763 or February 766 – 24 March 809 (148–193 Hijri)) was the fifth Abbasid Caliph.
His birth date is debated, with various sources giving dates from 763 to 766.
His epithet "al-Rashid" translates to "the Orthodoxthe Justthe Upright", or "the Rightly-Guided".
Al-Rashid ruled from 786 to 809, during the peak of the Islamic Golden Age.
He established the legendary library Bayt al-Hikma ("House of Wisdom") in Baghdad in present-day Iraq, and during his rule Baghdad began to flourish as a center of knowledge, culture and trade.
During his rule, the family of Barmakids, which played a deciding role in establishing the Abbasid Caliphate, declined gradually.
In 796, he moved his court and government to Raqqa in present-day Syria.
A Frankish mission came to offer Harun friendship in 799.
Harun sent various presents with the emissaries on their return to Charlemagne's court, including a clock that Charlemagne and his retinue deemed to be a conjuration because of the sounds it emanated and the tricks it displayed every time an hour ticked.
Portions of the fictional "One Thousand and One Nights" are set in Harun's court and some of its stories involve Harun himself.
Harun's life and court have been the subject of many other tales, both factual and fictitious.
Some of the Twelver sect of Shia Muslims blame Harun for his supposed role in the murder of their 7th Imam
(Musa ibn Ja'far).
