It is narrated from Sayyiduna Umar bin Abi Salamah (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) entered the house of Sayyidah Umm Salamah (may Allah be pleased with her) and saw with them an effeminate man (mukhannath), who was saying: O Abdullah bin Abi Umayyah! If Ta'if is conquered, I will show you Badiyah bint Ghaylan; she comes forward with four folds and turns away with eight folds (because of her plumpness). So the Prophet (peace and blessings be upon him) said: "These people must never enter upon you."
