Question
A woman conditioned her husband not to marry another wife, but then he did marry. The ruling was that the condition is void and has no value. Why are marriage conditions considered void and not valid?
Answer
I say, and with God's success: Because the marriage contract specifies the rights and duties of each spouse as determined by the Wise Legislator, and there is no need to add to it. If something is added, it would be unjust to the other party, including the husband's right to marry. No one has the authority to prevent him from doing so, as God Almighty has approved it and granted it to him. Preventing the husband from this is an infringement on his legal right, so the condition is considered void. And God knows best.
