Al-Ṭaḥāwī recorded it (2/391) through the route of Sulaymān ibn Shuʿayb who said: “ʿAbd al-Raḥmān ibn Ziyād narrated to us; he said: ‘Shuʿbah narrated to us from al-Jarīrī, who said: I heard Abū Naḍrah relating it from Abū Saʿīd.’ As for this Abū Saʿīd and ʿAbd al-Raḥmān ibn Ziyād, I do not know who they are. It is possible that the latter is ʿAbd al-Raḥmān ibn Ziyād ibn Anʿam al-Ifrīqī, and his ḥadith is weak.

It is disliked to call the ʿIshāʾ prayer al-ʿatamah (the late-night). The Prophet ﷺ said: “Do not let the Bedouins override you concerning the name of your prayer; it is al-ʿishāʾ, for in the Book of Allah it is al-ʿishāʾ. They only term it al-ʿatamah because they milk their camels late.” Muslim (118), Abū Dāwūd (2/312), al-Nasāʾī (93-94), Ibn Majah (239), and Aḥmad (2/10, 19, 49, 144) all transmitted it from ʿAbd Allāh ibn Abī Labīd, from Abū Salamah ibn ʿAbd al-Raḥmān, from Ibn ʿUmar.

In another wording recorded by Aḥmad: “They merely call it al-ʿatamah because they stay late with their camels.” Its chain is sound according to Muslim’s criteria.

A corroborating report from Abū Hurayrah is found in Ibn Majah, through the route of ʿAbd al-Raḥmān ibn Ḥurmulah from Saʿīd ibn al-Mīb, and its isnād is good; in the Zawāʾid it is graded authentic.

Yet another chain for the same ḥadith is reported by Ibn Majah and by Aḥmad (2/433, 438) from Muḥammad ibn ʿAjlān: “Saʿīd—meaning al-Maqburī—narrated to me from Abū Hurayrah,” in a brief version traced back to the Prophet; this chain is also hasan.

Thus, using the term al-ʿatamah on rare occasions is unobjectionable, since it is authentically established from him ﷺ in the statement: “If they only knew what is in al-ʿatamah…”
