The ruling on a menstruating woman abstaining if she becomes pure during the day

The questioner:
If a menstruating woman or a woman with post-natal bleeding becomes pure during part of the day in Ramadan, is she required to abstain for the remainder of it?

The Shaykh:
If a menstruating woman becomes pure during the day, she is required to abstain for the rest of the day, out of respect for the time, and she must make up that day, because she did not fast it in full.

The questioner:
Yes, some women get their period just moments after sunset, meaning after the Maghrib adhan is called, and they take precautions and make up that day. What is your opinion?

The Shaykh:
If the sun has set and no blood has come out of her, her fast is valid. However, if the blood comes out before the sun sets, she must make up that day because she did not complete it. Yes.

The questioner:
Is this not considered excessive piety, O Shaykh, if she reads it or something like that?

The Shaykh:
No, she does not make it up, because she fasted it. As long as the sun has set and no blood has come out of her, she has fasted a complete fast, so there is no need to make it up. Yes.
