He says: What are the conditions that are not allowed in the contract? It is not allowed to stipulate them, and the wife is not allowed to stipulate them.

Any condition that is not found in the Book is invalid, this is the principle.

And any condition that contradicts the purpose of marriage is invalid.

So if he stipulates, for example, that they do not want children, this is an invalid condition. If he stipulates that he will not spend on her, this is an invalid condition. If he stipulates that she does not have the right to housing, this is an invalid condition.

If she stipulates that she will not become pregnant, this is an invalid condition. If she stipulates that she will not allow him to enjoy her.

If she says you will not take your right from me, this is an invalid condition. Any condition that contradicts the essence of the contract is an invalid condition.
