A
      woman is pregnant with quadruplets; is it permissible for her to abort
      two?
Question

                There
      is a woman who cannot have children. The doctors examined her and
      discovered that her eggs were dead. They did an operation to transplant
      eggs and she became pregnant with four embryos. When the doctors
      discovered this and told her husband, he said that he did not want four
      children, because his wife might get too tired. He told them to abort two
      of them and leave two. The doctors said, “We will not do that unless we
      have a fatwa from Shaykh Muhammad ibn Saalih al-‘Uthaymeen.” The
      pregnancy has already lasted three months, so is it permissible for the
      doctors to do this operation, since they have agreed to wait for your
      opinion?
Praise be to Allah.We
      will not speak here about the operation to transplant eggs, since the
      matter is finished with in this case. With regard to aborting some of the
      foetuses which are in her womb, if there is any fear for the mother’s
      life and the fourth month of the pregnancy has not passed, then it is OK;
      if the pregnancy is past four months, then it is not permissible to abort
      any of the foetuses under any circumstances.
