Is it permissible to abort a fetus before it reaches forty days, given the presence of young children and circumstances that cause hardship in raising more of them?

Scholars have differed concerning the ruling on aborting a fetus before forty days. The preponderant opinion is that it is permissible when there is an excuse or a benefit, or to avert an anticipated harm. Therefore, it is not forbidden for the questioner to abort if the pregnancy causes her great hardship due to the succession of her births, the young age of her two daughters, her lack of assistance, and her instability. However, it is more preferable, if possible, to avoid abortion as a way of exiting the disagreement.
