Biography
Family
According to Yaqut al-Hamawi, the full lineage of Jassas ibn Murrah is in fact Jassas, son of Murrah, son of Dhal, son of Shayban, son of Tha'laba, son of Aqaba, son of Sa'b, son of Ali, son of Bakr ibn Wa'il; al-Hamawi proceeds to trace this lineage back to Adnan. Hence, Jassas is from the Banu Bakr and belongs to the Banu Shayban division of the tribe. Additionally, Jassas' descent from Adnan confirms that he is not only amongst the Adnanites, but also a descendant of the biblical patriarch Ishmael, and is of an Israelite mother at the same time.Jassas' sister, Jalilah bint Murrah, was married to Kulaib ibn Rabiah hence making him the brother-in-law of Kulaib. Jassas' nephew from Kulaib and Jalilah's marriage was al-Jarw ibn Kulaib. His maternal aunt was Al-Basus, who was the same woman whom incited him to kill Kulaib which started the 40-year Basus War.
Conflicts with the Taghlib
Igniting the Basus War
After Kulaib ibn Rabiah of the Taghlib tribe had shot a prized she-camel belonging to an influential woman affiliated with the Banu Bakr named Al-Basus, this action angered Jassas ibn Murrah. Jassas murdered Kulaib over this conflict, and this aroused the anger of the whole Taghlib tribe, who started to have an enmity against Jassas' tribe, the Banu Shayban and its parent tribe, Banu Bakr.The Taghlib fought against the Banu Bakr for 40 years, in the long series of conflicts known as the Basus War. The time period of this war has been dated to around 494–534 CE.
