1 – Ḥumayd reports from him:
The Prophet ﷺ once noticed phlegm on the qiblah wall, and the sight of it distressed him so much that it showed on his face. He rose and scraped it off with his hand, saying,
“When any one of you stands for prayer, he is conversing with his Lord—or his Lord is between him and the qiblah—so let none of you spit toward the qiblah. Rather, he should spit to his left or beneath his foot.”
He then took the edge of his cloak, spat into it, folded one part over the other and added, “Or he may do it like this.”

Al-Bukhārī, al-Dārimī, al-Bayhaqī, and Aḥmad all recorded this wording, and Aḥmad’s chain is triadic. Ḥumayd explicitly stated that he heard it from Anas in the version preserved by ʿAbd al-Razzāq, removing any concern about his tadlīs, as Ibn Ḥajar notes in Fatḥ al-Bārī.

2 – Qatādah relates it from Anas in abridged form, omitting the occasion of the report and the phrase “He then took …” and what follows.
This shorter version is found in al-Bukhārī, Muslim, al-Bayhaqī, al-Ṭayālisī, and Aḥmad through multiple chains. Qatādah likewise affirms having heard it from Anas in al-Bukhārī, and that is also the reading adopted by al-Bayhaqī and others.

Third: Abū Saʿīd al-Khudrī.
Four isnāds go back to him:
1 – al-Zuhrī → Ḥumayd ibn ʿAbd al-Raḥmān → Abū Saʿīd. This route has already appeared in the ḥadith of Abū
