In Islamic tradition al-Nadr was the ancestor of Muhammad.
The tradition holds that "Muhammad was the son of 'Abdullah, b. 'Abdu'I-Muttalib (whose name
was Shayba), b. Hashim (whose name was 'Amr), b. 'Abd Manaf (whose
name was al-Mughira), b. Qusay (whose name was Zayd), b. Kilab, b.
Murra, b. Ka'b, b. Lu'ay, b. Ghalib, b. Fihr, b. Malik, b. aI-Nadr, b.
Kinana, b. Khuzayma, b. Mudrika (whose name was 'Amir), b. Ilyas,
b. Mudar, b. Nizar, b. Ma'add, b. Adnan, b. Udd (or Udad),....
b. Ya'rub, b. Yashjub, b. Nabit, b. Isma'il b. Ibrahim, the friend of the Compassionate."
His father Kinana had four sons: al-Nadr, Malik, 'Abdu Manat, and Milkan. Nadr's mother was Barra d. Murr b. Udd b. Tabikha b. al-Yas b. Mudar; the other sons were by another woman.
It is said that Quraysh tribe got their name from their gathering Nadr (quraish) to his brothers after they had been separated, for gathering together may be expressed by taqarrush.
