The Ahabish tribes were a group of tribes who lived in and around Mecca and adopted a Bedouin lifestyle. These tribes had been recognised as the traditional allies of the Quraysh since pre-Islamic times, and they maintained their loyalty throughout the Risalah period. Contemporary scholars disagree on the origin of the Ahabish tribes. The reason for this disagreement is whether the word 'Abyssinia' is related to Abyssinia or not. However, these debates have not considered the literature of Ansab. This study will attempt to examine the origin of the Ehâbish tribes within the framework of pre-Islamic narratives through the genealogical tables in the Ansāb and Tabāq literature. To this end, we will first discuss the debates on the etymological origin of the word al-Ahābish, which have attracted the attention of contemporary scholars. We will then attempt to draw up a genealogy of these tribes through a comparative analysis of the scattered and incomplete information found in early Islamic historical sources. It will be concluded that al-Hāris b. ʿAbdumānāt b. Kināna, who is mentioned among the Ehābish tribes, is in fact al-Hāris b. Baqr b. ʿAbdumānāt b. Kināna, that these tribes were related to each other through Umm al-Hārīja, that they may have migrated from southern Arabia to Mecca in the mid-fourth century AD, and that their origins should have been in southern Arabia. Their origins should be seen as the social class of abnâ (sons), which arose from the intimacy they established with the local population after the Abyssinians conquered southern Arabia. The alliance (hilf) of these tribes with the Quraysh will make important contributions to the understanding of the culture of patronage in the Arab tribal tradition and to debates in the modern period.
