Asma daughter of Abu Bakr said: I heard a woman asking the Messenger of Allah صلی اللہ علیہ وسلم : What should any of us to with her clothe (in which she menstruated) when she becomes purified ? Can she pray in that (clothe) ? He said: She should see; if she finds blood in it, she should scratch it with some water and (in case of doubt) sprinkle upon it (some water) and pray so long as she does not find (any blood).
