Sahih al-Bukhari Book 67, Hadith 167
An Ansari woman came to the Prophet (ﷺ) and he took her aside and said (to her). "By Allah, you (Ansar)
are the most beloved people to me."
The Prophet (ﷺ) said, "No man should stay with a lady in seclusion except in the presence of a Dhu- Muhram." A man stood up and said, "O Allah's Messenger (ﷺ)! My wife has gone out intending to perform the Hajj and I have been enrolled (in the army) for such-and-such campaign." The Prophet (ﷺ) said, "Return and perform the Hajj with your wife."
that while the Prophet (ﷺ) was with her, there was an effeminate man in the house. The effeminate man said to Um Salama's brother, `Abdullah bin Abi Umaiyya, "If Allah should make you conquer Ta'if tomorrow, I recommend that you take the daughter of Ghailan (in marriage) for (she is so fat) that she shows four folds of flesh when facing you and eight when she turns her back." Thereupon the Prophet (ﷺ) said (to us), "This (effeminate man) should not enter upon you (anymore).
