It is narrated from Hazrat Abu Huraira (may Allah be pleased with him) that Khawla bint Yasar (may Allah be pleased with her) once came to the service of the Noble Prophet (peace and blessings be upon him) and said, "O Messenger of Allah (peace and blessings be upon him), I have only one garment and during my days of impurity, that is what I wear. What should I do?" The Noble Prophet (peace and blessings be upon him) said, "When you become pure, wash the place where the blood has stained and then pray in that same garment." She submitted, "O Messenger of Allah, what if the mark of the blood does not go away?" He replied, "Water is sufficient; it does not matter if the mark does not disappear."
