Is abortion permissible due to difficult financial circumstances?

Abortion is forbidden at any stage of the fetus's development, and the sin becomes graver after the ensoulment.

If the pregnancy is from a previous husband, marriage is not permissible before the 'iddah (waiting period) ends with the delivery of the pregnancy.

If the pregnancy is a result of zina (fornication/adultery), scholars have differed on marrying a pregnant woman. The more cautious approach is to avoid marrying her to avoid the disagreement, and the pregnancy is not attributed to the fornicator.
