A woman who had her menstrual period in Ramadan, and on the last days of the period she slept during the night while she had not yet become pure, and she intended that if she became pure she would fast

The questioner : A woman had her menstrual period in Ramadan. On the last days of the period she slept during the night while she had not yet become pure. She intended that if she became pure she would fast. She did not wake up until after Fajr, so she looked and found that she had become pure. Does she complete the fast and is it valid, or does she make up a day in its place?

The Shaykh : She must make up the fast; she has to make up a day in its place. This is because she slept with an uncertain intention. She did not know whether the obstacle to fasting, which is menstruation, would be removed or not. So she must now make up that day. If she had fasted that day, she would be rewarded for her intention. However, to clear her conscience, she must make up that day.
