It is narrated from Sayyida Aisha (RA) that the Messenger of Allah (peace and blessings be upon him) was asked about a person who finds wetness of semen but does not remember having a wet dream. The Prophet (peace and blessings be upon him) said: He should perform ghusl (ritual bath). Then he was asked about a person who thinks he had a wet dream but does not find any wetness. The Prophet (peace and blessings be upon him) said: There is no ghusl upon him. Sayyida Umm Sulaym (RA) said: If a woman has a similar dream, is the ruling the same for her? The Prophet (peace and blessings be upon him) said: Yes, women are like men.
