I say: Its narrators are trustworthy and appear among the narrators of the two Ṣaḥīḥs, except for ʿAlī ibn Zayd—namely Ibn Judʿān—who is weak because of his poor retention.
ʿAṭāʾ al-Khurāsānī also corroborated it from Saʿīd ibn al-Musayyib, in an abbreviated form, with the wording: “If she sees the fluid, then she must perform ghusl.” Al-Nasāʾī narrated it (1/42).
However, although this ʿAṭāʾ was truthful, he made many errors and practised tadlīs, as al-Ḥāfiẓ stated. My view is that, were it not for his use of an ambiguous “from” transmission, he would have been an unobjectionable supporting narrator for Ibn Judʿān.
Yet the hadith has corroborating reports that strengthen it. Among them is a similar hadith of ʿĀʾishah, which includes the Prophet’s words, peace and blessings be upon him: “Yes; women are but the counterparts of men.” It is an authentic hadith, as I have explained in Ṣaḥīḥ Abī Dāwūd (234).
2188 — “Nothing in Paradise resembles anything in this world except the names.”
Abū Nuʿaym narrated it in Ṣifat al-Jannah (21/2): Abū Muḥammad ibn Ḥayyān narrated to us; Abū Yaḥyā al-Rāzī narrated to us; Hannād ibn al-Sarī narrated to us; Abū Muʿāwiyah and Wakīʿ narrated to us from al-Aʿmash, from Abū Ẓabyān, from Ibn ʿAbbās, attributed to the Companion. Al-Ḍiyāʾ al-Maqdisī also narrated it in al-Mukhtārah (59/198/2), through the route of Abū Isḥāq Ibrāhīm ibn ʿAbd Allāh ibn ʿUmar ibn Bukayr al-ʿAbsī, who said: Wakīʿ narrated to us with the same chain.
I say: Both chains revolve around Wakīʿ, who is trustworthy and appears among the narrators of the two Ṣaḥīḥs; thus, the chain is authentic. Al-Mundhirī said in al-Targhīb (4/278): “Al-Bayhaqī narrated it with a good chain of transmission.”
