I said: He is truthful and his ḥadīth is considered good, being among the narrators of Muslim. There is some discussion about him, but his ḥadīth does not fall below the rank of ḥasan, if Allāh wills. However, his teacher al-Haytham ibn ʿAlqamah ibn Qays ibn Thaʿlabah is unknown to me, and I have not seen anyone mention him. I fear there might be some distortion in the narration. Abū Isḥāq al-Ḥarbī has recorded the ḥadīth in "Gharīb al-Ḥadīth" as follows: ʿAbd Allāh ibn ʿUmar narrated to us, Yūnus ibn Bukayr narrated to us from al-Haytham from ʿAṭiyyah ibn Qays from al-Azraq ibn Qays with it. Al-Ḥarbī is a trustworthy, reliable ḥāfiẓ, so his narration takes precedence over that of ʿAlī ibn Saʿīd al-Rāzī. Even though Muslimah ibn Qāsim considered him trustworthy, al-Dāraqutnī said: "He is not that [reliable]." His mention in the isnād: "al-Haytham ibn ʿAlqamah ibn Qays ibn Thaʿlabah" could be one of his errors if it is preserved from him, and the correct statement is that of al-Ḥarbī: "al-Haytham from ʿAṭiyyah ibn Qays." This al-Haytham is Ibn ʿImrān al-Dimashqī, who was deemed trustworthy by Ibn Ḥibbān. A group of trustworthy narrators have reported from him, as I verified in "the other book" under ḥadīth (967), where I elaborated on the legitimacy of relying on the hands when rising from the second prostration or the first tashahhud, and I mentioned there a strong corroborator for ʿAṭiyyah ibn Qays, so refer to it. It is astonishing that this ḥadīth is unknown to all who compiled works on "takhrīj," as I mentioned there. Even more astonishing is that al-Haythamī did not include it in "Majmaʿ al-Baḥrayn fī Zawāʾid al-Muʿjamayn," nor in "Majmaʿ al-Zawāʾid," even though he included what contradicts it. He said (2/136): "And from ʿAbd al-Raḥmān ibn Yazīd who said: I observed ʿAbd Allāh ibn Masʿūd in prayer and saw him rise without sitting. He would rise on the balls of his feet in the first and third rakʿah. It was narrated by al-Ṭabarānī in 'al-Kabīr,' and its men are the men of the ṣaḥīḥ."
