On the authority of his father, he said: The Messenger of Allah, peace and blessings be upon him, was asked about water and what frequents it of beasts and predators. He said: "If the water reaches two qullas, it does not carry impurity."(1)

(1) Its chain of transmission is authentic. Abu Usamah: he is Hammad ibn Usamah.

It was also narrated by Abu Dawud (63) from Muhammad ibn al-'Ala', 'Uthman ibn Abi Shaybah, and al-Hasan ibn 'Ali, and by Ibn Hibban (1249) via the path of Abu Bakr ibn Abi Shaybah, all four of them from Abu Usamah, from al-Walid ibn Kathir, from Muhammad ibn Ja'far ibn al-Zubayr, from 'Abd Allah (with the tafkhim) ibn 'Abd Allah ibn 'Umar, with it. Abu Dawud said: This is the wording of Ibn al-'Ala', and 'Uthman and al-Hasan ibn 'Ali said: Muhammad ibn 'Abbad ibn Ja'far. Abu Dawud said: That is correct.

It was also narrated by Ibn Hibban (1253) with his aforementioned chain in (1249) to al-Walid ibn Kathir, then he said: from Muhammad ibn 'Abbad ibn Ja'far, from 'Ubayd Allah (with the tasghir) ibn 'Abd Allah, with it.

It was also narrated by al-Hakim 1/133 and al-Bayhaqi 1/261 via the path of Abu Usamah, from al-Walid ibn Kathir, from Muhammad ibn Ja'far ibn al-Zubayr and Muhammad ibn 'Abbad ibn Ja'far (they separated the two), from 'Abd Allah ibn 'Abd Allah, with it. So he combined between Muhammad ibn Ja'far and Muhammad ibn 'Abbad. Al-Hakim said: He narrated it (i.e., Abu Usamah) once from this one and once from that one.

It was also narrated by Ahmad (4605), (4803), and (4961), Abu Dawud (64), al-Tirmidhi (67), and Ibn Majah (517) via the path of Muhammad ibn Ishaq, from Muhammad ibn Ja'far ibn al-Zubayr, from 'Ubayd Allah ibn 'Abd Allah, from his father. Ibn Ishaq explicitly stated his direct hearing (al-tahdith) in al-Tabari's "Tahdhib al-Athar" (1111) (Musnad Ibn 'Abbas) and in al-Daraqutni's "Sunan" (17), thus removing any suspicion of his tadlis.

This discrepancy in mentioning Muhammad ibn Ja'far and Muhammad ibn 'Abbad, and in mentioning 'Abd Allah and 'Ubayd Allah, is not a damaging inconsistency (idtirab), as mentioned by al-Hafiz Ibn Hajar in "al-Talkhis al-Habir" 1/17, and he said: Even if all of it is presumed preserved, it is a transmission from one trustworthy narrator to another trustworthy narrator. See the rest of his discussion on it, and also see the discussion on the hadith in al-Musnad (4605), and the hadith will be repeated under number (328).

It was also narrated by Ahmad (4753), Abu Dawud (65), and Ibn Majah (518) via the path of Hammad ibn Salamah, from 'Asim ibn al-Mundhir, from 'Ubayd Allah ibn 'Abd Allah, from his father, with it, in abbreviated form, and in Ahmad and Ibn Majah: "two qullas or three." Al-Bayhaqi said in "al-Sunan al-Kubra" 1/262: The narration of the group who did not express doubt is more appropriate.
