It was asked from Sayyida Aisha (may Allah be pleased with her) about the semen that gets on the clothes. She replied that I used to wash the semen from the clothes of the Messenger of Allah (peace and blessings be upon him). Then he would go out for prayer and the mark of washing (that is, the spots of water) would remain on his clothes.
