And under “The Warnings against Breaking the Fast in Ramadan” he writes:

1 – On the authority of Ibn ʿAbbās, the Messenger of Allah ﷺ said, “The supports of Islam … .”

I say: The author already cited this report in the chapter on abandoning the prayer, and there I demonstrated its weakness; repeating that discussion is unnecessary.

2 – On the authority of Abū Hurayrah, the Prophet ﷺ said, “Whoever breaks the fast for a single day of Ramadan without a concession that Allah has granted him, the fasting of an entire lifetime would not make it up, even if he were to observe it.” Abū Dāwūd, Ibn Mājah, and al-Tirmidhī transmitted it, and al-Bukhārī said, “It is related from Abū Hurayrah with a marfūʿ chain … .”

I say: The hadith is weak. Al-Bukhārī hinted at that by employing the expression “it is related,” and Ibn Khuzaymah judged it weak in his Ṣaḥīḥ (3/238), as did al-Munḏhirī, al-Baghawī, al-Qurṭubī, al-Dhahabī, and al-Damīrī, according to what al-Manāwī reports, as well as Ibn Ḥajar. Ibn Ḥajar listed three defects: inconsistency, an unknown narrator, and a break in the chain; see Fatḥ al-Bārī 4/161.

He nevertheless erred when he said, “Ibn Khuzaymah authenticated it.” The correct wording is: Ibn Khuzaymah recorded it in his Ṣaḥīḥ but weakened it in the chapter heading, saying, “If this report is authentic, I do not know Ibn al-Miṭwās or his father.”

A likewise serious error was committed by one of our brothers—may Allah guide him—in his work “The Sound Hadiths Selected from Ṣaḥīḥ al-Bukhārī.” He did not realize that in al-Bukhārī the narration is merely suspended (muʿallaq), and that al-Bukhārī’s muʿallaq reports are not all deemed authentic by him, let alone by others; indeed, this is one that al-Bukhārī himself implicitly weakened, as I have just explained. I drew his attention to this in the book’s first edition, and he promised to rectify it. I do not know whether he has since managed to reprint the work and remove the report in fulfillment of that promise; I had thought well of him.
