Malik said: So among the proofs against the one who says that statement is to say to him: What do you think if a man claims money against another man—does not the one being claimed from swear an oath that this right is not upon him? If he swears, that claim is nullified against him. But if he refuses to swear, the owner of the right is made to swear that his right is indeed true, and his right is established against the other. This is something about which there is no disagreement among any of the people, nor in any land among the lands. So by what was this taken? Or in what place in the Book of Allah did he find it? If he acknowledges this, then let him acknowledge the oath along with the witness. And if that is not in the Book of Allah, Mighty and Majestic, then what has passed from the Sunnah is sufficient for that. But a person may wish to know the aspect of correctness and the place of the proof. So in this is clarification of what is problematic from that, if Allah, Exalted is He, wills.
