[1] He lived in Medina at the time of Abu Hanifa and Ja'far al-Sadiq and studied in Al-Masjid an-Nabawi as a student of Malik ibn Anas.

Al-Waqidi originally earned a living as a wheat trader, but when a calamity struck at the age of 50, he migrated to Iraq during the reign of Harun ar-Rashid.

[1] His books on the early Islamic expeditions and conquests predate much of the Sunni and Shia literature of the later Abbasid period.
