From Sahih Bukhari (Hadith 5887):
Narrated Um Salama:that once the Prophet (ﷺ) was in her house, and an effeminate man was there too. The effeminate man said to `Abdullah, (Um Salama's brother) "0 `Abdullah! If Ta'if should be conquered tomorrow, I recommend you the daughter of Ghailan, for she is so fat that she has four curves in the front (of her belly) and eight at the back." So the Prophet (ﷺ) said (to his wives) "These effeminate (men) should not enter upon you (your houses)
