‘Ā'ishah (may Allah be pleased with her) reported: I used to wash the traces of semen from the garment of the Messenger of Allah (may Allah's peace and blessings be upon him) and he would go out to the prayer with water spots on his garment (i.e. before his garment is totally dry). Another narration reads: "I used to rub it well off the garment of the Messenger of Allah (may Allah's peace and blessings be upon him) and then he would pray wearing it."
