it seems that this is the basis for al-Haythamī's authentication of him by saying in "al-Majmaʿ" (8/6): "It was narrated by Aḥmad, and its men are the men of the authentic [collections] except for ʿUmar ibn ʿAbd al-Raḥmān ibn ʿAṭiyyah, and he is trustworthy."

- "Leave it aside — meaning the cushion — if you can prostrate on the ground, otherwise gesture and make your prostration lower than your bowing." It was narrated by al-Ṭabarānī in "al-Muʿjam al-Kabīr" (3/189/2): ʿAbd Allāh ibn Aḥmad ibn Ḥanbal narrated to us: Shabāb al-ʿAṣfarī narrated to me, Sahl Abū ʿAtāb informed us, Ḥafṣ ibn Sulaymān informed us from Qays ibn Muslim from Ṭāriq ibn Shihāb from Ibn ʿUmar who said: "The Messenger of Allāh (ṣallá Allāhu ʿalayhi wa-sallam) visited a sick man from his companions, and I was with him. He entered upon him while he was praying on a stick, and he placed his forehead on the stick. He gestured to him to remove the stick, and he took a cushion, and the Messenger of Allāh (ṣallá Allāhu ʿalayhi wa-sallam) said..." and he mentioned it. I say: This isnād is authentic; all its men are trustworthy, and here is the explanation: First: Ṭāriq ibn Shihāb, who is Abū ʿAbd Allāh al-Kūfī, a minor Companion, saw the Prophet (ṣallá Allāhu ʿalayhi wa-sallam), but did not hear from him, and he narrates frequently from ʿAbd Allāh ibn Masʿūd (raḍiya Allāhu ʿanhu). He was relied upon by the two Shaykhs and the authors of the four Sunan. Second: Qays ibn Muslim, who is Abū ʿAmr al-Kūfī al-Jadalī, is trustworthy and was also relied upon by the six. Third: Ḥafṣ ibn Sulaymān. He is either Ḥafṣ ibn Sulaymān al-Asadī Abū ʿAmr al-Bazzār al-Kūfī al-Qārī, or Ḥafṣ ibn Sulaymān al-Munqarī al-Tamīmī al-Baṣrī. If it is the former, he is abandoned in ḥadīth, and if it is the latter, he is trustworthy. Each possibility has its justification,
