Ḥuyayy, from Abū ʿAbd al-Raḥmān, from ʿAbd Allāh ibn ʿAmr, who said:

The Messenger of Allah, peace and blessings be upon him, appointed a man to lead the people in the noon prayer. While leading them in prayer, he spat in the direction of the qiblah. When it was time for the afternoon prayer, he sent for another man. The first man became apprehensive, so he came to the Prophet, peace and blessings be upon him, and said, “O Messenger of Allah, peace and blessings be upon him, has anything been revealed concerning me?” He said: ... and then cited it.

I say: This is a good chain of transmission. Its narrators are trustworthy, and their biographies appear in al-Tahdhīb, though there is slight weakness in Ḥuyayy—who is Ḥuyayy ibn ʿAbd Allāh al-Maʿāfirī al-Miṣrī—apart from Ismāʿīl ibn al-Ḥasan, whom I have not identified. He was al-Khaffāf al-Miṣrī, and al-Ṭabarānī narrated extensively from him in Kitāb al-Duʿāʾ, relating through him fourteen hadiths, as stated in the introduction of its editor, Dr al-Bukhārī (1/187). He also related through him two hadiths in al-Awsaṭ (4/5–6), and one hadith in al-Ṣaghīr (715—al-Rawḍ), most of them from this Aḥmad ibn Ṣāliḥ—the Egyptian hadith master. He must have narrated very extensively from him in al-Muʿjam al-Kabīr. Thus, he is among those whose like al-Dhahabī indicated may be accepted in some of the biographies in his Mīzān. It seems to be for this reason that al-Mundhirī said in al-Targhīb (1/122/9):

“Al-Ṭabarānī narrated it in al-Kabīr with a good chain of transmission.”

Al-Haythamī said (2/20):

“Al-Ṭabarānī narrated it in al-Kabīr, and its narrators are trustworthy.”

It also has a corroborating report, with similar wording, from Abū Sahlah al-Sāʾib ibn Khallād, narrated by Abū Dāwūd and Ibn Ḥibbān. It is referenced in Ṣaḥīḥ Abī Dāwūd, no. 501, and in al-Taʿlīq al-Raghīb (1/122/8). The hadith master made no comment on it in al-Fatḥ (1/508).

Note: As you have seen, the hadith is narrated by ʿAbd Allāh ibn ʿAmr, but in al-Targhīb it occurs:
