Answer
In the Name of Allah, Most Gracious, Most Merciful.
All praise and thanks are due to Allah, and peace and blessings be upon His Messenger.
In this fatwa:
1- Abortion is not permissible except for valid medical reasons. In the early days of pregnancy, committing abortion is less grave than committing it after 120 days of conception.
2- In your case, you need to consult reliable physicians and act according to their medical advice.
In responding to your question, Sheikh Ahmad Kutty, a senior lecturer and an Islamic scholar at the Islamic Institute of Toronto, Ontario, Canada, states:
If your doctor recommends that pregnancy for your wife in her specific condition will have adverse effects on her health, then she may undergo abortion at this early phase.
Abortion after 120 days is akin to taking a life, for that is the time when the soul is breathed into the fetus; abortion before that is sinful unless there are reasons warranting it; the health challenges of the mother can be one of those conditions.
Allah Almighty knows best.
