If one Agrees with an Oath that is Taken, it Dismisses his Claim even if he has Testimony

“Abu ‘Abd Allah (a.s.), has said, ’If a plaintiff agrees with the defendant’s taking an oath who then swears that the plaintiff does not have any right on him, it abolishes the right of the plaintiff and the case is dismissed.’ I then asked, ‘What happens if he can present just testimony?’ He (the Imam) said, ‘Yes, even so, an oath by Allah fifty times abolishes and invalidates his claim because of which he had asked for an oath.’”

“About the case of a man who has a certain right on another man who denies it, abu ‘Abd Allah (a.s.), has said, ‘If he has made him to take an oath, then he does not have any right; but if he has not made him to take an oath, then his right is in place.’”

“This is about the case of a man to whom another man owes a certain amount of assets who denies and takes an oath that he does not owe him anything; if he (plaintiff) must be content with it or there is any remedy for him? He (the Imam) (a.s.), has said, ‘He does not have any right thereafter and so also is the case if he (plaintiff) waives it for the sake of Allah, he does not have any right to ask for it anymore.’”
