The main religion of the Kababish is Sunni Muslim, but it is said that due to their nomadic lifestyle where water is short they are not strict followers of their religion's practices.
During the dry season some clans migrate to the desert area of the Kababish tribe to the west (Khala' Kabushiyah, خلاء كبوشية) others to the grazing grounds of Wad Hamid (بادية ود حامد) in the Ga'ali Country (الجعليين) or to the Rubatab (الرباطاب) Country.
