Imām Aḥmad said:

Bahz and ʿAffān narrated to us, saying: Ḥammād ibn Salamah narrated to us;
who said: ʿUqayl ibn Abī Ṭalḥah related to me.
ʿAffān added: ʿUqayl ibn Ṭalḥah al-Sulamī, on the authority of Muslim ibn al-Hayḍam, from al-Ashʿath ibn Qays, who said:

I came to the Messenger of Allah ﷺ as part of the Kindah delegation—ʿAffān comments, “lest they think me their superior.” I said, “O Messenger of Allah, we claim that you are one of us.”

The Messenger of Allah ﷺ replied:
“We are the children of al-Naḍr ibn Kinānah; we neither attribute ourselves to an unknown mother nor repudiate our father.”(1)

Al-Ashʿath ibn Qays then said, “By Allah, if I ever hear anyone sever Quraysh from al-Naḍr ibn Kinānah, I shall inflict upon him the prescribed punishment.”(2)

Ibn Mājah likewise transmitted this ḥadīth through several chains from Ḥammād ibn Salamah with the same wording.(3) This chain is sound and strong; it is decisive in this matter, so no attention is due to anyone who opposes it. Allah knows best, and to Him belong praise and favor.

Jarīr ibn ʿAṭiyyah al-Tamīmī(4) composed the following verses in praise of Hishām ibn ʿAbd al-Malik ibn Marwān:

The mother who bore Quraysh is neither base of stock nor barren,
No noble surpasses your father in lineage,
Nor is any maternal uncle more honored than Tamīm.

Ibn Hishām commented: He means the mother of al-Naḍr ibn Kinānah—Barrah bint Mur, the sister of Tamīm ibn Mur.(5)

As for the derivation of the name “Quraysh,” it is said to come from taqarrush, meaning “to gather after dispersion.” This took place in the time of Quṣayy ibn Kilāb; they had been scattered, and he assembled them in the Sacred Precinct, as will be detailed later. Ḥudhāfah ibn Ghānim al-ʿAdawī(7) said:

Your forefather Quṣayy was called “the Gatherer”;
Through him Allah united the tribes descended from Fihr.

Others maintain that Quṣayy himself was called “Quraysh” because of this gathering; taqarrush signifies assemblage, as Abū Jildah al-Yashkurī(8) said
