tribe and the Quraysh
tribe are considered ‘Adnani Arabs.
Much of the lineage provided before Ma'ad
relies on biblical genealogy, so questions persist concerning the accuracy of this segment of Adnanite Arab genealogy.
According to Parolin, the Adnanites are believed to be the descendants of Ishmael through Adnan but the traditional Adnanite lineage doesn't match the biblical line exactly. According to Arab tradition, the Adnanites are called Arabised because it is believed that Ishmael was speaking Hebrew
and he got married from a Qahtanite Yemeni woman and learnt Arabic from her. Therefore, the Adnanites are descendants of Abraham. According to Parolin, Modern historiography "unveiled the lack of inner coherence of this genealogical system and demonstrated that it finds insufficient matching evidence".
there are rules and laws that are used among tribes. According to legends, in ancient times, seventy tribal leaders (Sheikhs) met with each other and came up with these rules.
