It is also noted that the agreed lineage of the Ja'aliyyin includes some ancestors from its descendants, such as Yaman al-Khazraji and Dhu Akla' al-Himayri, who is Ibn Sa'd al-Ansari, attributed to his mother al-Ansariyyah. However, it continues thereafter to al-Abbas, As'ad al-Ansari, son of al-Fadl, son of Abdullah, son of Abbas. Many tribes have branched off from the Ja'aliyyin, which were under their banner, including: The Jawabra Tribe: They are attributed to a great-grandfather named Jabir, and their main center is in the island of Badin, located in the middle of the Nile, south of the line separating the Mahas and Dongola to the south. It appears that their homeland was more extensive in Burckhardt's era, as he mentioned that it extended from the First and Second Cataracts. They were lovers of knowledge and learning. From this, some of Jabir's sons migrated to Egypt in search of knowledge. They were four: the most knowledgeable was Ibrahim, the most pious was Abd al-Rahman, the most eloquent was Ismail, and the most devout was Abd al-Rahman. These trace their lineage to Ghulām Allah. They returned to Sudan to contribute to the Islamic cultural and intellectual movement. We find that one of them, Sheikh Ibrahim bin Jabir, known as al-Bulad, settled in the village of Tarnah and taught there. He was the first to teach the Risala, and people traveled to him. His school in Khalil had seven pages and he taught forty people, all of whom became saints and poles, by the will of Allah Almighty. The lineage of these sons of Jabir traces back to Ghulām Allah al-Yamanī. The Jawabra are the most numerous tribe there, extending from the Hannek Cataracts to Hilla al-Titi, and include the kingdoms of Argo, the island of Maqasir, and al-Khatag. The inhabitants of this region were a mixture, mostly Jawabra and Nubians, with a trace of the Kenozi; and Egyptian immigrants. (Burckhardt) says that the Jawabra tribe and the Gharbiyyah, the latter being a branch of the great Zanatiyyah tribe that settled the land from 211
