This appears to be al-Haythami’s basis for declaring him trustworthy when he said in al-Majmaʿ (8/6):

“Ahmad narrated it, and its narrators are those of the Ṣaḥīḥ collections, apart from ʿUmar ibn ʿAbd al-Raḥmān ibn ʿAṭiyyah, who is trustworthy.”

323 — “Put it aside”—meaning the cushion—“if you are able to prostrate on the ground; otherwise, gesture, making your prostration lower than your bowing.”

Al-Ṭabarānī recorded it in al-Muʿjam al-Kabīr (3/189/2): ʿAbd Allah ibn Aḥmad ibn Ḥanbal related to us: Shabāb al-ʿUsfurī related to me: Sahl Abū ʿAttāb informed us: Ḥafṣ ibn Sulaymān informed us, from Qays ibn Muslim, from Ṭāriq ibn Shihāb, from Ibn ʿUmar, who said:

“The Messenger of Allah, peace and blessings be upon him, visited one of his Companions who was ill, and I was with him. He entered upon him while he was praying on a piece of wood, placing his forehead upon it. So he gestured to him, and the man cast the wood aside and took a cushion. The Messenger of Allah, peace and blessings be upon him, then said …” He then cited the wording above.

I say: This is an authentic chain of transmission; all of its narrators are trustworthy. Here is the explanation:

First: Ṭāriq ibn Shihāb, Abū ʿAbd Allah al-Kūfī, was a junior Companion. He saw the Prophet, peace and blessings be upon him, but did not hear from him. He narrated extensively from ʿAbd Allah ibn Masʿūd, may Allah be pleased with him. Both al-Bukhārī and Muslim, as well as the authors of the four Sunan, relied upon him.

Second: Qays ibn Muslim, Abū ʿAmr al-Kūfī al-Jadalī, was trustworthy. The six major hadith compilers likewise relied upon him.

Third: Ḥafṣ ibn Sulaymān. He is either Ḥafṣ ibn Sulaymān al-Asadī, Abū ʿUmar al-Bazzār al-Kūfī, the Quran reciter, or Ḥafṣ ibn Sulaymān al-Minqārī al-Tamīmī al-Baṣrī. If he is the former, his hadith is abandoned; but if he is the latter, he is trustworthy. There is a basis for each of the two possibilities,
