Umm Sulaym, the mother of Anas bin Malik, asked the Prophet ﷺ, "Messenger of Allah, what about a woman who sees in her dream what a man sees?"The Messenger of Allah ﷺ replied to her, "If a woman sees that and experiences a discharge, she must perform the ritual bath."
حدثنا أبو عبد الرحمن حدثنا ابن عمر يعني عبد الجبار الأيلي حدثنا يزيد بن أبي سمية سمعت
سألت أم سليم وهي أم أنس بن مالك النبي ﷺ فقالت يا رسول الله ترى المرأة في المنام ما يرى الرجل فقال لها رسول الله ﷺ إذا رأت المرأة ذلك وأنزلت فلتغتسل
Its isnad is daif. Abdul-Jabbar bin Umar Ayli is daif. Ibn Saad gave his biography in al-Tabaqat 7/2/207 and said, "He was reliable." Bukhari gave his biography in al-Saghir, 195, and said, "He has odd narrations," and mentioned him in al-Duafa, 24, and said, "He is not strong according to them." Nasai also mentioned him in al-Duafa, 21. Ibn Abu Hatim gave his biography in al-Jarh wal-Tadil 3/1/31-32, and reported from Ibn Main who said, "Daif, of no worth," and from his father Abu Hatim, "Weak in hadith, very odd in hadith, though not one whose position amounts to lying." He also related that Abu Zura weakened him, and Abu Dawud, Tirmidhi, and others also declared him daif.Yazid bin Abu Sumayya Ayli is reliable. Abu Zura and others declared him reliable, and Bukhari gave his biography in al-Kabir 4/2/338.The hadith appears in Majma al-Zawaid 1:267, where it is said, "Ahmad narrated it, and it contains Abdul-Jabbar bin Umar Ayli, whom Ibn Main and others declared daif, while Muhammad bin Saad declared him reliable." Its meaning is sahih. Abu Dawud narrated it, 1:96, from the hadith of Ayesha. Munziri said, 229, "Muslim and Nasai also related it." Bukhari, Muslim, Tirmidhi, Nasai, and Ibn Majah related it from the hadith of Umm Salama, wife of the Prophet ﷺ. See also al-Muntaqa, 379-381.
