Rabbi Yehudah says: [The husband] can always eat the fruits' fruit [i.e. the interest's interest, even if he said in the ketubah that he gives up access to the fruit from her property]. How so? He can sell the fruit and buy with [that money] land, and he can eat the fruit. Rabban Shimon ben Gamliel and Rabbi Yohanan ben Berokah say: If she dies, he inherits it [the fruit, even if he said he wouldn't have access to it in the ketubah], for she made a stipulation against what was written in the Torah and anyone who stipulates against what is written in the Torah, his stipulation is null and void.
