'Ailan was named Fazara because Sa'd bin Dhubyan, his brother, injured his back, and Fazara was thus named. Fazara comprises several clans, such as Banu Shamkh, Dhalam, Murra, Mazin, Shakm, Sa'd, Ludan, and others. Some of Fazara settled in Upper Egypt, and some migrated to Sudan, belonging to the Qays tribe. From the study of this Fazara group, at least in the narratives of Dar Hamid, there appears to be a connection to Banu Hilal. The narratives of Dar Hamid, through which a branch of Fazara passed, state that their ancestor Hamid, upon arriving in western Sudan, met Abu Zayd al-Hilali and consulted him about the place to settle. Abu Zayd advised him to inhabit a specific spot in Kordofan. The Ziyadiyya also, to this day, trace their lineage to Abu Zayd al-Hilali. Also added to these tribes belonging to the Juhayna branch are the Dawiyha al-Sulaymiyya, al-Baqqara, al-Mahamid, al-Kababish, al-Manaziya, and al-Humr. Genealogists have named Fazara a group of tribes living in the eastern and central regions of Kordofan. This group consists of several clans, including Dar Hamid, Banu Jarar, al-Ziyadiyya, al-Naz'a, al-Shanabla, and al-Ma'aliya. Some of these clans are involved in camel husbandry. If we look at the Fazara tribe in Sudan today, we find that its cohesion has dissolved, and they have become separate units, each unit bearing its own name. Among the Baqqara tribes is the Banu Sulaym tribe. They are divided into two branches: Umm Tarif and Awlad Majub. They live west of the White Nile in an area extending south to Kaka, north of the Shamluk and Dinka regions, and south of the Ajamid. Their main occupation is cattle herding. In the rainy season, they move north and east of the river, fleeing the effects of the fly. Some have resorted to raising goats and have increased their numbers due to their migration towards the river.
