A girl was fasting during Ramadan and became impure (due to the release of moisture) but did not know how to identify the signs of impurity (reaching a point of pleasure and bodily fatigue). She thought at that time that she was not impure and continued to fast the remaining days without performing a ritual purification. Is she required to make up the fast? And is there a penalty to be paid? If so, what is the value of the penalty?
