Mukhtasar Muslim

Umm al-Mu’minin Aisha Siddiqa (may Allah be pleased with her) says that a mukhannath (effeminate man) used to come to the wives of the Messenger of Allah (peace and blessings be upon him), and they considered him among those who have no interest in women (and in the Qur’an, it is permitted for such people to appear before women). One day, the Messenger of Allah (peace and blessings be upon him) came to one of his wives, and he (the mukhannath) was describing a woman, saying: “When she comes forward, she comes with four folds, and when she turns her back, eight folds become visible.” The Messenger of Allah (peace and blessings be upon him) said: “He recognizes those who are here (i.e., he likes and distinguishes the beauty and ugliness of women); do not let him come to you.” (Sayyida Aisha says) So they stopped him from coming.
