of a tree, let him chew it.” (1)

This is a good (ḥasan) hadith.

The meaning of “disliked” here is that a man should single out Saturday for fasting, because the Jews venerate Saturday.

44 – Chapter: What has been reported about fasting on Monday and Thursday

755 – Abū Ḥafṣ ʿAmr ibn ʿAlī al-Fallās narrated to us, he said: ʿAbd Allāh ibn Dāwūd narrated to us, from Thawr ibn Yazīd, from Khālid ibn Maʿdān, from Rabīʿah al-Jurashī, from ʿĀʾishah, who said: The Prophet, peace and blessings be upon him, would be keen to fast on Monday and Thursday. (2)

(1) Its narrators are trustworthy, except that it was deemed defective due to inconsistency and contradiction, and we have elaborated on this in our commentary on “Musnad Aḥmad” (17686) and “Ṣaḥīḥ Ibn Ḥibbān” (3615).
It was also narrated by Abū Dāwūd (2421), Ibn Mājah following the hadith (1726), and al-Nasāʾī in “al-Kubrā” (2760) and (2762) and after it, and it is in “al-Musnad” (27075).
It is stated in “al-Furūʿ” 3/123–124 by Ibn Mufliḥ, with the following text: al-Athram said: Abū ʿAbd Allāh — Imam Aḥmad — said: A hadith of al-Ṣammāʾ has come regarding this, and Yaḥyā ibn Saʿīd was wary of it and refused to narrate it to me. Al-Athram said: Abū ʿAbd Allāh’s evidence regarding fasting on Saturday is that all the hadiths contradict the hadith of ʿAbd Allāh ibn Busr, among them the hadith of Umm Salamah.
Ibn Mufliḥ said: Our teacher — meaning Shaykh al-Islām Ibn Taymiyyah — chose that it is not disliked to fast it, that this is the view of most scholars, and that this is what al-Athram understood from their narration, and that if singling it out were intended, then obligatory fasting would not have been included to be exempted, so the hadith is anomalous (shādhdh) or abrogated.
(2) A sound (ṣaḥīḥ) hadith, narrated by Ibn Mājah (1739) and al-Nasāʾī 4/202 and 203. =
