Sahih Muslim | Book 26 | Hadith Number 5415

Narrated by Umm Salama
Umm Salama reported that she had a eunuch (as a slave) in her house. Allah's Messenger imay peace be upon him) was once in the house that he (the eunuch) said to the brother of Umm Salama: Abdullahb. Aba Umayya; if Allah grants you victory in Ta'if on the next day, I will show you the daughter of Ghailan for she has four folds (upon her body) on the front side of her stomach and eight folds on the back. Allah's Messenger (may peace be upon him) heard this and he said: Such (people) should not visit you.
