Asma daughter of Abu Bakr said: A woman asked the Messenger of Allah صلی اللہ علیہ وسلم: Messenger of Allah, what do you think if the clothe of any of us smeared with the blood of menstruation; what should she do ? He said: If (the clothe of) any of you is smeared with blood of menstruation, she should scratch it; then she should sprinkle water upon it and then she may pray.
