Technical note / Defect ('illah): All its narrators are thiqah (trustworthy); however, there is disagreement over it from Imam al-Zuhri: some narrated it through him from Sa'id bin al-Musayyab as "mursal", and some made it "mawquf" on Sa'id bin al-Musayyab (his own statement).
Note / Clarification: Yahya bin Yahya is Ibn Bukayr al-Naysaburi, and Sufyan is Sufyan bin Uyaynah.

Reference / Source: Musaddad narrated it (as in "al-Matalib al-Aliyah": 1464) by way of Sufyan bin Uyaynah, with this same chain, as "mursal".

Details of the narration: Ibn Abi Shaybah (6/374), Ibn Zanjawayh in "al-Amwal" (1078), Abu Dawud in "al-Marasil" (402) and al-Bayhaqi (6/155) narrated it through various routes from Sufyan al-Thawri, from Isma'il bin Umayyah, as "mursal".

Details of the narration: Musaddad also narrated it by way of Ziyad bin Sa'd, and Sadaqah bin Abdullah bin Kathir corroborated him (as in al-Daraqutni's "al-Ilal": 1693). Both of them narrate it from al-Zuhri as "mursal".

Details of the narration: The following narrated it as "mawquf" on Sa'id bin al-Musayyab: Yahya bin Adam in "al-Kharaj" (327) (and through him al-Bayhaqi 6/155) by way of Yunus bin Yazid; Ibn Abi Shaybah (6/374) by way of Ma'mar; and Abu Ubayd in "al-Amwal" (729) and Ibn Zanjawayh (1079) by way of al-Layth bin Sa'd. All three of these narrators narrate it from al-Zuhri, from Sa'id bin al-Musayyab.

Note / Clarification: See also the narration after it.

Important point: The word "البادي" occurs in the text, whereas in some sources it is narrated as "البديء" and in others as "البدية". Ibn al-Athir writes in "al-Nihayah" that "al-badi'" (on the pattern of badi') is a well that was dug in the Islamic era and is not an ancient one ('adiyyah).

General principle: Ibn Zanjawayh says in "al-Amwal" (2/653): "al-badiyyah" is a well whose digging was begun in Islam, while "al-'adiyyah" is one that dates from ancient times.
