Is it permissible for a woman to marry her male servant, by analogy with the permissibility of a man marrying his slave woman (milk al-yamin)? What is the ruling on one who excuses such a person due to their ignorance? And is this considered irja'?

A woman is not permitted to enjoy her male slave. The questioner about the ruling on this matter asked about a legal ruling, the ignorance of which does not constitute a sin, because it is a communal obligation (fard kifaya). And whoever says that he is excused by ignorance bears no sin, and this is not considered a postponement [of judgment].
