It is narrated from Sayyida Umm Salama (may Allah be pleased with her) that Sayyida Umm Sulaim, the wife of Sayyiduna Abu Talha (may Allah be pleased with him), said: O Messenger of Allah! If a woman sees in a dream that her husband is having intercourse with her, does she have to perform ghusl (ritual bath)? The Prophet (peace and blessings be upon him) said: Yes, when she sees the discharge of semen. Sayyida Umm Salama (may Allah be pleased with her) said: Does a woman also have discharge? The Prophet (peace and blessings be upon him) said: May your right hand be dusted! The resemblance of the child to the maternal uncles is due to this discharge of the woman; whichever of the two fluids precedes towards the womb, that one prevails in resemblance. In the narration of Hajjaj, it is: May your forehead be dusted.
