The ruling on fasting for a woman who miscarried due to heavy labor

The Shaykh:
May Allah grant you a good evening.

The questioner:
May you live long, Shaykh. My mother is quite old now. She says that twenty-five years ago, she was pregnant in her second month. She says she was working with her goats and in her house, and she overexerted herself. She says she miscarried. So she asks: Does she have to fast for the day she miscarried, or do you think she should? May Allah reward you for your answer.

The Shaykh:
Her question.

The questioner:
The question again, O Muhammad. Muhammad. She is now advanced in age. Yes. And twenty-five years ago, she was two months pregnant. She says she worked in her house. She says she overburdened herself. She says she miscarried. She says, "Was I the cause of the miscarriage through the work, through the labor in the house?" She says, "Do I have to fast, or do I not have to fast?" All right, thank you. Her mother, twenty-five years ago, Honorable Shaykh, worked and overburdened herself with heavy labor, so she miscarried, and now she asks: does she owe anything after this period?

The Shaykh:
How old was the fetus when it was expelled?

The questioner:
Two months, Shaykh Salih.

The Shaykh:
Two months.

The questioner:
Yes.

The Shaykh:
Meaning, the soul was not breathed into it.

The questioner:
Yes, Shaykh.

The Shaykh:
There is nothing [owed], but she erred in this. However, there is nothing [owed] because the soul was not breathed into it, yes.
