Akk ibn Adnan
According to tradition, Adnan is the father of a group of the Ishmaelite Arabs who inhabited West and Northern Arabia; he is a descendant of Ishmael, son of Abraham. Adnan is believed by genealogists to be the father of many Ishmaelite tribes along the Western coast of Arabia, Northern Arabia and Iraq.
Some Arab historians[who?] have proposed his ancestry as thus: Adnan ibn U'dud ibn Sind ibn Ya'rub ibn Yashjub ibn Nabeth ibn Qedar ibn Ishmael ibn Abraham ibn Azar (Terah) ibn Nahur ibn Serug ibn Reu ibn Peleg ibn Eber ibn Salah ibn Arpachshad ibn Shem ibn Noah ibn Lamech ibn Methuselah ibn Idris (Enoch) ibn Jared ibn Mahalalel ibn Kenan ibn Enos ibn Seth ibn Adam.
Many family trees have been presented by Adnan, which did not agree about the number of ancestors between Ishmael and Adnan but agreed about the names and number of the ancestors between Adnan and the Prophet Muhammad.
The overwhelming majority of traditions and Muslim scholars state that Adnan is a descendant of Kedar the son of Ishmael, except for Ibn Ishaq who claimed that Adnan was a descendant of Nebaioth, this confusion of Ibn Ishaq can be because one of the descendants of Kedar was also named "Nebaioth".
Adnan had two sons, Ma'ad ibn Adnan and Akk ibn Adnan. Akk dwelt in the Yaman because he took a wife amongst the Asharites and lived with them, adopting their language. The Asharites were descend from Saba' ibn Yashjub ibn Ya'rub ibn Qahtan.
Adnan was viewed by Pre-Islamic Arabs as an honorable father among the fathers of Arab tribes, and they used this ancestry to boast against other Qahtani tribes who were a minority among the Adnanites.
"Layla Bent Lukayz", a Pre-Islamic female poet, was captured by a Persian king and forced to marry him, so she composed a poem designated to other Arab tribes, asking for their help and reminding that she and them all belong to Adnan, which makes it a duty for them to rescue her.
In other poems such as the ones composed by the Pre-Islamic poet "Qumma'a Ibn Ilias", it appears that Arabs considered it as a "Honor" to be a descendant of Adnan, and for some reason they appear to have been proud of it.
The name of Adnan was found many times in various Thamudic inscriptions, but with few details. In some Nabataean inscriptions, Adnan seems to hold some kind of importance or venerability, to the extent that some Nabataean people were named after him as "Abd Adnon" (The Servant/Slave of Adnan). There is no particular indication that he was worshiped, except as an honorable figure, exactly as some other Arabs called some of their sons as "servants" of their fore-fathers.
Adnan died after Nebuchadnezzar II returned to Babylon. After Adnan's death, his son Ma'ad moved away to the region of Central-Western Hijaz after the destruction of the Qedarite kingdom near Mesopotamia, and the remaining Qedarite Arabs there were displaced from their lands and forced to live in Al-Anbar province and on the banks of the Euphrates river under the rule of the Neo-Babylonian Empire.
According to Islamic tradition, the Islamic prophet Muhammad was descended from Adnan. "The following is the list of chiefs who are said to have ruled the Jazeera and to have been the intraline ancestors of Muhammad."
