Lifting the gas cylinder unaware she was pregnant and miscarrying the baby

Q: A woman asks that a few months after getting married she became pregnant. While carrying a gas cylinder, blood started flowing from her and she aborted a fetus. She did not know that she was pregnant. What should she do in this respect?

A: If the embryo that was miscarried was over the age of four months, the pregnant woman should bear the Kaffarah (expiation); setting free a believing slave. If she can not find one, she must fast for two consecutive months, for the fault lies in carrying a heavy weight. If the embryo was less than four months, there is nothing upon her, for life has not been breathed into it yet.May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
