Umm Salama told that once when the Prophet was with her there was in the house a hermaphrodite who said to Abdallah b. Abu Umayya, Umm Salama's brother, “If God conquers at-Ta'if for you tomorrow, I shall lead you to the daughter of Ghailan who has four folds of fat in front and eight behind.” Thereupon the Prophet said, “Do not let these people visit you.”
