All praise and thanks are due to Allah, and peace and blessings be upon His Messenger.
In this fatwa:
In the case of multiple embryos, it is not permissible to kill some and save some. However, if there are some unhealthy embryos that might cause death to others, then some competent doctors should decide to remove the dangerous embryo. But this must be done with great care and only in the case of actual, not perceived, danger.
In his response to the question, Dr. Muzammil Siddiqi, former president of the Islamic Society of North America, states:
According to all jurists, abortion is allowed in the situation when mother’s life is at an actual risk.
In the case of multiple embryos, it is not permissible to kill some and save some. However, if there are some unhealthy embryos that might cause death to others, then some competent doctors should decide to remove the dangerous embryo. But this must be done with great care and only in the case of actual, not perceived, danger.
It is the basic principle of the Shari`ah that when there are two harms, then one should choose the lesser harm.
In this situation, there are two harms present: either to lose all the embryos or lose some. If this is the only choice, then the dangerous and unhealthy embryos can be aborted.
In the case of actual risk to the life of the mother, there is no time limit. Before the birth anytime, abortion can be done as long as the risk is actual, not just imagined or perceived.
Allah Almighty knows best.
