Narrated from Sayyida Aisha (may Allah be pleased with her) that a eunuch used to come to the wives of the Prophet Muhammad (peace and blessings be upon him). People thought that he was free from carnal desires. One day, when the Prophet Muhammad (peace and blessings be upon him) arrived, that eunuch was present with one of his wives. He began to describe the beauty of a woman, saying that when she comes, she comes with four folds, and when she goes, she goes with eight folds. Upon hearing this, the Prophet Muhammad (peace and blessings be upon him) said: I did not know that he knows so much. He should not be allowed to come to you in the future. So the people forbade him.
