Is zakat al-fitr paid on behalf of a fetus, and how much is paid?

Question : And if we say it is paid on behalf of all of them, how much is paid: one sa' or two sa'as?

Answer : There is a possibility that it is a fetus. We have stated in the law of inheritance that if a man dies leaving a fetus, the larger share is reserved for it, as if it were two males or two females, as a precaution. It is said that the default is that this is a right belonging to a created being, so precaution is required in it. As for this, it is a right belonging to Allah, and the default is that the conscience is free from liability, so it is not paid except on behalf of one fetus.
