As for the hadith of Zayd, the freedman of the Messenger of Allah, Bilāl ibn Yasār ibn Zayd narrates it from his father, from his grandfather, ascribed to the Prophet, with the same wording, except for the phrase “three times.” It was transmitted by Abū Dāwūd, al-Tirmidhī, Ibn Abī Khaythamah in al-Tārīkh (250—Islamic University facsimile), and Ibn Saʿd (7/66). Al-Tirmidhī deemed it strange, and al-Mundhirī considered its chain good. However, it contains an unknown narrator, as I explained in Ṣaḥīḥ Abī Dāwūd (1358); yet it is authentic in light of what precedes and follows it.

As for the hadith of Abū Bakr, ʿUrwah ibn Zuhayr al-Bajalī narrates it from Thābit al-Bunānī, from Anas ibn Mālik, from him, with the same wording. Ibn ʿAdī transmitted it in al-Kāmil (folio 260/1) and said: “I know of no hadith from this ʿUrwah other than this one. Al-Bukhārī said: ‘No one corroborates him in it.’” Al-ʿUqaylī (3/364) reported that al-Bukhārī said: “His hadith is rejected.” As for Ibn Ḥibbān, he included him among the trustworthy narrators (7/288)!

As for the hadith of Abū Hurayrah, Bishr ibn Rāfiʿ narrates it from Muḥammad ibn ʿAbd Allāh, from his father, from him, ascribed to the Prophet, with the same wording. Abū Nuʿaym transmitted it in Akhbār Iṣbahān (2/303). I say: This is a weak chain of transmission because of the weakness of Bishr ibn Rāfiʿ. I could not identify Muḥammad ibn ʿAbd Allāh. It is possible that he is Muḥammad ibn ʿUbayd Allāh—with ʿUbayd in the diminutive form—namely, Muḥammad ibn ʿUbayd Allāh ibn Abī Rāfiʿ al-Hāshimī, their freedman; for his father narrated from Abū Hurayrah. If he is indeed the same person, then he too is weak.
