Hisham ibn Abd al-Malik

Hisham ibn Abd al-Malik (72-125 AH / 691-743 CE) was the tenth Umayyad caliph, whose nineteen-year reign was the dynasty's last long one. A careful administrator, he reorganised the diwans, the police and the postal service while the frontiers stopped advancing.

Muhammad ibn Ali (56 or 57–114 AH), called al-Baqir, was a son of Zayn al-Abidin and a grandson of both al-Hasan and al-Husayn. He taught hadith and law in Medina and is the fifth Imam of the Twelver Shi'a.
