It also has a corroborating report from Jābir, similar to Ibn ʿUmar’s first hadith. Sufyān al-Thawrī narrated it from Abū al-Zubayr, from Jābir.
Al-Bazzār recorded it (p. 66 of its supplementary narrations), as did al-Bayhaqī. Its chain consists of trustworthy narrators, and it contains no hidden defect that would undermine its authenticity, apart from Abū al-Zubayr’s ambiguous use of “from,” for he practised tadlīs. On this basis, al-Ḥāfiẓ ʿAbd al-Ḥaqq al-Ishbīlī declared it defective in his Aḥkām (no. 1383, in my edition). Nevertheless, al-Ḥāfiẓ Ibn Ḥajar stated in his Bulūgh that it is strong. Allah knows best.
What is beyond doubt is that the hadith is authentic when all its chains are considered together. Allah Most High is the One who grants success.
Abū ʿAwānah narrated in his Musnad (2/338) from ʿUmar ibn Muḥammad, who said:
“We entered upon Ḥafṣ ibn ʿĀṣim to visit him while he was ill. He related to us, saying: ‘My uncle ʿAbd Allah ibn ʿUmar entered upon me and found that I had placed a small cushion before me—that is, a pillow—and spread a small mat over it, upon which I was prostrating. He said to me: “My nephew, do not do this. Place your face upon the ground; and if you are unable to do so, then gesture with your head.”’”
Its chain is authentic according to the conditions of al-Bukhārī and Muslim.
324 — “Whoever alienates a servant from her household is not of us, and whoever turns a woman against her husband is not of us.”
Imām Aḥmad recorded it (2/397): Abū al-Jawwāb narrated to us: ʿAmmār ibn Ruzayq narrated to us, from ʿAbd Allah ibn ʿĪsā, from ʿIkrimah, from Yaḥyā ibn Yaʿmar, from Abū Hurayrah, who said: The Messenger of Allah
