“Salām al-Ṭawīl is abandoned in hadith, and no one else transmitted it with a chain going back to the Prophet.”
I say: Zayd al-ʿAmī is weak.
1178 — “Whoever dishonours Quraysh, Allah will dishonour him.”
It has been narrated from ʿUthmān ibn ʿAffān, Saʿd ibn Abī Waqqāṣ, Anas ibn Mālik, and ʿAbd Allāh ibn ʿAbbās.
1 — As for the hadith of ʿUthmān, it is narrated by ʿUbayd Allāh ibn Muḥammad ibn Ḥafṣ ibn ʿUmar ibn Mūsā ibn ʿAbd Allāh ibn Maʿmar al-Taymī, who said: I heard my father say: I heard my uncle, ʿUbayd Allāh ibn ʿUmar ibn Mūsā, say: Rabīʿah ibn Abī ʿAbd al-Raḥmān narrated to us, from Saʿīd ibn al-Musayyib, from ʿAmr ibn ʿUthmān ibn ʿAffān, who said: My father said to me: “My son, if you are entrusted with any matter concerning the people, then honour Quraysh, for I heard the Messenger of Allah, may Allah bless him and grant him peace, say”—then he mentioned it.
It was recorded by Ibn Ḥibbān (2288), Ibn ʿAsākir in Tārīkh Dimashq (13/291/1), and al-Ḍiyāʾ al-Maqdisī in al-Aḥādīth al-Mukhtārah (1/138), all through the route of Abū Yaʿlā; and by al-ʿUqaylī in al-Ḍuʿafāʾ (270), al-Ḥākim (4/74), Aḥmad likewise (1/64), and al-Ḍiyāʾ also in al-Muntaqā min Masmūʿātihi bi-Marw (29/1 and 112/2), through several routes from ʿUbayd Allāh with this chain.
Ibn ʿAsākir said: “It is a singular hadith.” Al-ʿUqaylī explained the reason for this, saying: “ʿUbayd Allāh ibn ʿAmr ibn Mūsā al-Taymī is not corroborated in his hadith. It has also been narrated through another chain of transmission, one similar to this.”
I say: Ibn Ḥibbān alone declared him trustworthy, while al-Dhahabī said: “There is some weakness in him.” Muḥammad ibn Ḥafṣ, too, was not declared trustworthy by anyone other than Ibn Ḥibbān. Al-Ḥusaynī said: “He is subject to scrutiny.”
2 — As for the hadith of Saʿd, it is narrated by Muḥammad ibn Abī Sufyān, from Yūsuf ibn al-Ḥakam, from Muḥammad ibn Saʿd, from his father, attributed to the Prophet with the wording: “Whoever seeks the humiliation of Quraysh, Allah will humiliate him.”
