It is permissible for a menstruating woman to wash her husband’s head, and comb his hair; her leftovers are pure (tahir); and regarding reclining in her lap and reciting Qur’an
While the Messenger of Allah (ﷺ) was in the mosque, he said: O 'A'isha, get me that garment. She said: I am menstruating. Upon this he remarked: Your menstruation is not in your hand, and she, therefore, got him that.
