Ismāʿīl was contradicted by Baqiyyah ibn al-Walīd; he said: from al-Zubaydī from Luqmān ibn ʿĀmir from ʿĀmir ibn Jushayb from Khālid ibn Maʿdān with it; except that he did not say: "from his sister al-Ṣammāʾ," and he inserted ʿĀmir ibn Jushayb between Luqmān and Khālid. Ibn Jushayb was deemed reliable by al-Dāraquṭnī, so this is a strong corroboration from Ibn Jushayb were it not for the ʿanʿanah of al-Walīd. However, there is a very strong corroboration narrated by three trustworthy narrators from Thawr ibn Yazīd from Khālid ibn Maʿdān with it, similar to the narration of al-Ḥakam ibn Nāfiʿ. It is cited in (al-Irwāʾ). I have mentioned for it therein a sound witness from the ḥadīth of Abū Umāmah, raised [to the Prophet]; so whoever wishes to review it may do so there. The purpose of citing the ḥadīth here, after we had verified the discussion on it there in "al-Irwāʾ" with citation and authentication, is to verify the discussion on this route of al-Ḥakam ibn Mūsá from Ismāʿīl from ʿAbd Allāh ibn Dīnār from Abū Umāmah. And now it seems to me that it is not far-fetched that Ismāʿīl did not err in his isnād from Abū Umāmah; as long as others have also narrated it from him as I mentioned earlier. And Allāh knows best. If you understand what has been presented; it is an injustice to the sunnah and a deviation from it for some contemporaries to hastily doubt the authenticity of this ḥadīth, let alone assert its weakness; not to mention claiming that it is a lie! And Allāh is the one whose help is sought. Then I found for it a supporting witness or another route, narrated by Aḥmad (6/368): Ḥasan ibn Mūsá told us, he said: Ibn Lahīʿah told us, he said: Mūsá ibn Wardān told us, he said: ʿUmayr ibn Jubayr (!) the client of Khārijah informed me: that the woman who asked the Messenger of Allāh (ṣallá Allāhu ʿalayhi wa-sallam) about fasting on Saturday told him: that she asked the Messenger of Allāh (ṣallá Allāhu ʿalayhi wa-sallam) about that? He said: "Neither for you, nor against you."
