'A'isha reported that a eunuch used to come to the wives of Allah's Apostle ( صلی اللہ علیہ وسلم ) and they did not find anything objectionable in his visit considering him to be a male without any sexual desire. Allah's Apostle ( صلی اللہ علیہ وسلم ) one day came as he was sitting with some of his wives and he was busy in describing the bodily characteristics of a lady and saying: As she comes in front four folds appear on her front side and as she turns her back eight folds appear on the back side. Thereupon Allah's Apostle ( صلی اللہ علیہ وسلم ) said: It seems that he knows these things; do not, therefore, allow him to cater. She ('A'isha) said: Then they began to observe veil from him.
