Abu Dawud said: And Abu al-Walid al-Tayalisi narrated it—though I did not hear it from him—from Sulayman ibn Kathir, from al-Zuhri, from 'Urwah, from 'A'ishah: Zaynab bint Jahsh experienced prolonged menstrual bleeding, and the Prophet, peace and blessings be upon him, said to her: "Perform ghusl for every prayer." And he related the hadith in full.

Abu Dawud said: And 'Abd al-Samad narrated it from Sulayman ibn Kathir, who said: "Perform wudu for every prayer."

Abu Dawud said: This is an error on the part of 'Abd al-Samad, and the correct statement is that of Abu al-Walid. (1)

293 — 'Abdullah ibn 'Amr ibn Abi al-Hajjaj Abu Ma'mar narrated to us: 'Abd al-Warith narrated to us, from al-Husayn, from Yahya ibn Abi Kathir, from Abu Salamah, who said:

--------------------------------------------
(1) The author's statement here was transmitted by al-Bayhaqi in his "Sunan" 1/350, who said after it: The narration of Abu al-Walid is also not well-preserved, for Muslim ibn Ibrahim narrated it from Sulayman ibn Kathir just as the rest of the narrators narrated it from al-Zuhri.

Then al-Bayhaqi produced it via the chain of Muslim ibn Ibrahim, from Sulayman ibn Kathir, from al-Zuhri, from 'Urwah, from 'A'ishah: The sister of Zaynab bint Jahsh experienced prolonged menstrual bleeding for seven years... and he mentioned it without saying in it that he commanded her to perform ghusl for every prayer. Then al-Bayhaqi said: This is more appropriate because it agrees with the rest of the narrations from al-Zuhri, and the narration of Muhammad ibn Ishaq from al-Zuhri is an error because it contradicts the rest of the narrations from al-Zuhri and contradicts the sound narration from 'Irak ibn Malik, from 'Urwah, from 'A'ishah. We say: The narration of al-Zuhri has preceded under numbers (285), (288), (290), and (291), and the narration of 'Irak has preceded under number (279).

And the sister of Zaynab bint Jahsh is Umm Habibah bint Jahsh, as explicitly stated in the preceding narration under number (288). See also the commentary on "al-Musnad" (27445).
