What is the ruling on a woman who intended to fast to make up a missed fast but hesitated about completing this fast?

The questioner : The sister intended to fast to make up a fast that was obligatory upon her, but now she is hesitating about whether to complete this day.

The Shaykh : Why?

The questioner : For no reason.

The Shaykh : Is she fasting to make up for what is owed to her?

The questioner: Yes.

The Shaykh : Okay, and did she eat the pre-dawn meal?

The questioner : Yes, my Shaykh.

The Shaykh : And what do you mean by the hesitation that occurred to her?

The questioner : She says for no reason, meaning she is hesitating in her intention: should she complete the fast or break it for this day?

The Shaykh : No, it means she is not hesitating in her intention; she is hesitating about persevering in the fast or breaking it.
Abu Layla : Yes, exactly.

The Shaykh : That is how it is understood from her.
Abu Layla : Yes, that is what she says.

The Shaykh : So she is not hesitating in her intention; her intention was valid and her pre-dawn meal was valid. Now it is like the one who says, "I put one foot forward and the other back," should she remain fasting or break the fast, like that?
Abu Layla : Yes, like that.

The Shaykh : Okay, now we understand that she has hesitation. So what is the question? Does she mean it is permissible for her to break the fast or not? Does she mean this hesitation invalidates her fast or not? What do you mean by the question?
Abu Layla : You have done well, O our Shaykh, both of them, and may Allah reward you.

The Shaykh : And may Allah reward you. As for her hesitation about whether to break the fast or continue with the fast, that does not invalidate her fast.
