I am pregnant with four twins since two months although I didn't have childbearing potential during the last four years. In addition, the doctor specialized in reprusccusions, already has notified me about the possible reprusccusions as a result of being pregnant with four twins as follows: abortion, Metrorrhagia, Premature birth, high blood pressure, gestational diabetes and the like. What is the ruling on aborting some of the aforementioned embryos? A medical report was attached in which the status of my question is clarified.
All perfect praise be to Allah, The Lord of The Worlds, and may His peace and blessings be upon our Prophet Muhammad and upon all of his family and companions.
If the existence of the four embryos leads to critical reprusccusions/or threat on mother's health, life or a possibility of aborting all of them, then aborting one/two/three is permissible mitigate the above mentioned risks so long as the ages of the embryos don't exceed four months. And Allah Knows Best.
