Sulaymān ibn Mūsá - and slaughtering "says: 'the days of slaughter,'" Ibn Jurayj says it. I said: This isnād is authentic, all its narrators are trustworthy, but it does not include the phrase: "and slaughtering," which is the point of reference. Rather, it includes that Ibn Jurayj narrated it from Sulaymān ibn Mūsá, meaning it is mursal because he did not mention its isnād. Thus, it is a strong mursal witness for the previously connected chains. Al-Bayhaqī said: "Muʿāwiyah ibn Yaḥyá al-Ṣadafī narrated it from al-Zuhrī from Saʿīd ibn al-Musayyib—once—from Abū Saʿīd and once from Abū Hurayrah (raḍiya Allāhu ʿanhum) from the Prophet (ṣallá Allāhu ʿalayhi wa-sallam) with it." Then he provided its isnād to him, and said: "Abū Aḥmad ibn ʿAdī said: Whether he said from al-Zuhrī from Saʿīd from Abū Hurayrah, or he said: from al-Zuhrī from Ibn al-Musayyib from Abū Saʿīd, both are not preserved, and no one narrates them except al-Ṣadafī." Al-Bayhaqī said: "Al-Ṣadafī is weak, he is not relied upon." I said: In "al-Taqrīb": "Weak, and what he narrated in Shām is better than what he narrated in Rayy." I said: This is from his ḥadīth in Shām, as Muḥammad ibn Shuʿayb narrated it from him, and he is Ibn Shābūr al-Dimashqī. Therefore, Abū Ḥātim exaggerated when he said, as his son narrated in "al-ʿIlal" (2/38): "This is a fabricated ḥadīth according to me!" The correct view according to me is that it does not fall below the level of ḥasan with the previous witnesses, especially since a group of Companions have said it, as in "Sharḥ Muslim" by al-Nawawī, and "al-Majmūʿ" by him (8/390)
