Technical note / Defect ('illah): In manuscript (Z) it is written "al-Muharimi" (with a mim), which is a distortion (error); the correct word is "al-Muharibi" (with a ba), as in manuscript (S) and others
Reference / Source: Several imams of the Sirah and the Maghazi mentioned this man among the delegation of Banu Muharib, such as Ibn Sa'd in "al-Tabaqat" (1/ 258) and Ibn al-Athir in "Usd al-Ghabah" (2/ 330).

Grading: The hadith is "sahih"
Technical note / Defect ('illah): This chain is weak because Muhammad bin Zurarah is majhul (unknown), since only Zayd bin al-Hubab narrated from him; Abdah bin Abd Allah also narrated through the chain of Zayd bin al-Hubab from Muhammad bin Zurarah that al-Muttalib bin Abd Allah said: I said to Banu Sawa' bin al-Harith: your father is the one who denied the pledge to the Messenger of Allah (peace and blessings be upon him)…
Reference / Source: Ibn Mandah narrated it in "Ma'rifat al-Sahabah" (1/ 809) and, from him, Abu Nu'aym in "al-Ma'rifah" (3564)
Important point: In the narration of Muhammad bin Zurarah this (mention of the father) is more likely, because Imam al-Zuhri contradicted him (as passed in the previous route) and narrated it from Umarah bin Khuzaymah from his uncle; so he narrated it from Umarah's uncle and not from his father, even though Umarah narrates a number of other hadiths from his father, and Allah knows best.

Reference / Source: Imam al-Bayhaqi narrated it at (10/ 146) through Abu Abd Allah al-Hakim, with this same chain.

Reference / Source: Ibn Abi Shaybah narrated it in his "Musnad" (19), al-Bukhari in "al-Tarikh al-Kabir" (1/ 87), Ibn Abi Asim in "al-Ahad wa al-Mathani" (2084), Abu Ya'la in "al-Musnad al-Kabir" (al-Matalib al-Aliyah 4019/3), Ibn al-Mundhir in "al-Awsat" (6752), al-Tabarani in "al-Kabir" (3730), Abu Nu'aym in "Ma'rifat al-Sahabah" (2357), al-Khatib in "al-Asma' al-Mubhamah" (p. 121-122) and "Mudih Awham al-Jam' wa al-Tafriq" (2/ 106), Ibn Asakir in "Tarikh Dimashq" (16/ 366), Ibn Bashkuwal in "Ghawamid al-Asma'" (p. 360) and Ibn al-Athir in "Usd al-Ghabah" (2/ 331), through various routes from Zayd bin al-Hubab
Note / Clarification: Some of them gave the name of the Bedouin as "Sawa' bin Qays", but al-Hafiz Ibn Hajar says in "al-Isabah" (3/ 251) that this is an error (wahm); then he mentioned the narration of al-Muttalib bin Abd Allah, in which the name comes as "Sawa' bin al-Harith", which is the narration of the majority.
