“that he narrated only one hadith.”
I say: He is referring to what al-Shaʿbī narrated: Abū Jubayrah ibn al-Ḍaḥḥāk told me:
“Concerning us—the Banū Salimah—the verse was revealed: ‘Do not insult one another with nicknames.’ He said: The Messenger of Allah, peace and blessings be upon him, came to Madinah, and there was not a man among us who did not have two or three names. Whenever one of them was called by one of those names, they would say, ‘O Messenger of Allah, he is offended by this.’ So the verse was revealed: ‘Do not insult one another with nicknames.’”
It was narrated by Aḥmad (4/260) and others, and authenticated by al-Tirmidhī (4/187), al-Ḥākim (2/463), and al-Dhahabī. All of this indicates that they considered Abū Jubayrah’s status as a Companion to be the stronger view, as is apparent from his statement, “Concerning us, it was revealed.” And Allah knows best.
The hadith was also narrated by al-Ḥākim in al-Kunā, as stated in al-Fatḥ al-Kabīr, which did not attribute it to anyone else.
His expression, nasam al-sāʿah (“the first breath of the Hour”): al-Nihāyah states: “It is derived from nasīm, the first faint stirring of a gentle wind; that is, I was sent at the beginning of the signs of the Hour, while its coming was still faint. It has also been said that it is the plural of nasamah, meaning: I was sent among living souls whom Allah, Exalted is He, created before the Hour drew near—as though he had said: toward the end of the emergence of the descendants of Adam.”
I say: Thus, it has the same meaning as the other hadith: “I was sent before the Hour.”
809 — “I was sent from the best generations of the descendants of Adam, generation after generation, until I was sent from the generation to which I belonged.”
It was narrated by al-Bukhārī (4/151—al-Nahḍah edition), Aḥmad (2/373 and 417), and Ibn Saʿd.
