Is it permissible for a Muslim female doctor who supports her family to work in a mixed hospital examining both men and women, or to work in a family planning center that is restricted to women but requires her to perform or participate in abortions if the fetus is not older than twelve weeks?

The fundamental principle is to seek work that does not involve mixing with men or participating in abortions. However, if there is a need and no other work is available, it is permissible to work in hospitals that do not mandate participation in forbidden abortion procedures. One should be cautious about mixing as much as possible, limiting it to the extent of the need, while ensuring that it does not lead to something forbidden.
