I say: in this matter Nuʿaym erred with respect to its chain of transmission.
Nuʿaym also stood alone in relating that denounced report: “Sufyān ibn ʿUyaynah narrated to us—from Abū al-Zinād, from al-Aʿraj, from Abū Hurayrah—traced back to the Prophet ﷺ: ‘You are living in a time when, should a person abandon even one-tenth of what he has been commanded, he will perish; yet a time will come upon my community when whoever acts on one-tenth of what he has been commanded will be saved.’ (1) I have no idea where Nuʿaym obtained this!”
Nuʿaym himself said, “People reject this ḥadith. I was sitting with Sufyān; something came up and he objected to it, after which he narrated this report to me.” (2)
I say: he is truthful in claiming that he heard the wording from Sufyān, yet it appears—Allah knows best—that Sufyān merely uttered it spontaneously, without any chain. The chain he had cited actually belonged to another ḥadith he intended to relate; when he encountered this denounced statement he expressed surprise, made his remark directly after the isnād, and Nuʿaym assumed that the chain belonged to that saying—Allah knows best.
Nuʿaym ibn Ḥammād further reported: “Ibn al-Mubārak and ʿAbdah ibn Sulaymān narrated to us—from ʿUbayd Allāh, from Nāfiʿ, from Abū Hurayrah—that the Messenger of Allah ﷺ used to pronounce the takbīr seven times in the first rakʿah and five times in the second on the two ʿĪds, all of them before the recitation.”
The correct stance is that this narration is mawqūf (3); no one raised it to the Prophet ﷺ except Nuʿaym, and he was mistaken in doing so.
