Commentary for Ketubot 167:1

וסבר רב תנאו קיים והא איתמר האומר לחבירו על מנת שאין לך עלי אונאה רב אמר יש לו עליו אונאה ושמואל אמר אין לו עליו אונאה

But does Rav hold that one’s condition [though contrary to what is written in the Torah] is valid? Has it not in fact been stated: If a man says to another, “[I will sell you this object] on condition that you have no claim for overcharging against me:” Rav said: He has the right to make a claim for overcharging; Shmuel says: He does not have a right to claim overcharging.
