Is the failure to abort the fetus, when the parents demand its abortion, considered disobedience to parents, given that the young man and woman desire to marry after their repentance?

Firstly: It is not permissible to abort a fetus after the ensoulment, except if there is a real danger to the mother's life. The ensoulment occurs after four months of pregnancy, and aborting it thereafter is a grave crime.

Secondly: If a woman becomes pregnant through zina (fornication/adultery), it is not permissible to contract marriage with her until she repents and delivers her child, according to the Maliki and Hanbali schools. However, the Hanafi and Shafi'i schools permit contracting marriage with her and having intercourse with her if the zina was committed by him (the husband).

Thirdly: The majority of scholars hold that the child born of zina is not attributed to the zani (fornicator/adulterer). Some scholars, like Sheikh Al-Islam Ibn Taymiyyah, are of the view that it is permissible to attribute the child to the zani if the woman was not firash (a legally married wife).
