Grading: This hadith is "sahih li-ghayrihi".
Technical note / Defect ('illah): This chain is "hasan" because of 'Uthman bin Salih al-Sahmi and Yahya bin Ayyub al-Ghafiqi, and both of them have corroboration. Moreover, the narrator Humayd al-Tawil explicitly stated elsewhere that he heard from Anas (may Allah be pleased with him), which removes the suspicion of his "tadlis".

Reference / Source: Imam Ibn Hibban (630) and al-Diya' al-Maqdisi in "al-Ahadith al-Mukhtarah" (volume 6, hadith numbers 2088 and 2091) narrated it by various routes from 'Uthman bin Salih al-Sahmi, with this same chain.

Reference / Source: Al-Bazzar narrated it in his "Musnad" (6622) via 'Amr bin Malik, and al-Diya' al-Maqdisi in (2090) via Khalid bin 'Abd al-Salam al-Sadafi; both of them from 'Abd Allah bin Wahb. Imam al-Bazzar says that, to our knowledge, no one other than Yahya bin Ayyub narrated it with the chain Humayd from Anas, and that it is known from Anas only through this route.

Reference / Source: Ibn Sam'un narrated it in "al-Amali" (24) and al-Diya' al-Maqdisi in (2089) with the chain 'Amr bin al-Rabi' bin Tariq from Yahya bin Ayyub.

Technical note / Defect ('illah): Imam Ibn 'Adi reported it in "al-Kamil" (volume 7, page 211) by two routes with the chain Yahya bin Rashid al-Mazini from Humayd al-Tawil, and said that only Yahya bin Ayyub and Yahya bin Rashid narrated it from Humayd.
Important point: Although Yahya bin Rashid is weak, his narration is taken into consideration in corroborating chains and supporting reports (mutaba'at and shawahid).

Technical note / Defect ('illah): Ibn 'Adi (volume 1, page 200) also narrated it with the chain Marwan bin Mu'awiyah from Humayd al-Tawil, but this chain is not reliable because it contains a narrator named Ahmad bin Muhammad bin Harb, whom Ibn 'Adi and Ibn Hibban declared a "liar" (kadhdhab).

Technical note / Defect ('illah): Ibn 'Adi also reported it with the chain Qatadah from Anas, but the same lying narrator (Ibn Harb) is in it too, which is why Ibn 'Adi declared both these routes "batil" (false). Al-Khatib al-Baghdadi also reported it in "Mudih Awham al-Jam'" (1/ 258) with the chain Abu Sa'd al-Baqqal from Anas, but this chain is weak and contains an error, because this narration of al-Baqqal is actually the hadith of Ibn Mas'ud, whose takhrij is given in "Musnad Ahmad" (volume 6, hadith 3568).

Note / Clarification: See the previous narration.
