Abaq ibn Ays

Abaq ibn Ays — link number 19 of the disputed part of the Prophet's lineage, counting up from Adnan toward Ismail; his son is عيص بن ماخي and his father عيص in the well-known transmission of Ibn Ishaq and al-Kalbi ^{1 2}.

He sits between عيص بن ماخي and عيص in the chain running «Adnan ibn Udd ibn Adad ibn al-Humaysa ibn Salman ibn Awf ibn Buz ibn Qamwal ibn Ubayy ibn al-Awwam ibn Nashid ibn Haza ibn Bildas ibn Yadlaf ibn Tabikh ibn Jahim ibn Nahish ibn Makhi ibn Ays ibn Abaq ibn Da'id ibn Nabt ibn Mashih ibn al-Nashtan ibn Udr ibn al-Dhara' ibn Abd ibn Ahmar ibn Nabit ibn Qaydar ibn Ismail ibn Ibrahim», as transmitted by Ibn Sa'd and al-Tabari with variant names at several points ^{3 2}.

The sira and genealogy scholars divide the Prophet's lineage in three: a part agreed as sound down to Adnan, a part disputed between those who suspend judgement and those who affirm it from Adnan up to Ibrahim, and a part above Ibrahim to Adam that certainly contains unsound matter ⁴. This link belongs to the second part, and many genealogists stop at Ma'add ibn Adnan on the strength of the report «the genealogists lie» — see Stopping the genealogy at Ma'add.

Abaq ibn Ays is a name in the chain of the Prophet's ancestors between Adnan and Ismail; scholars do not confirm this part of the lineage because the reports disagree.
