When is an oath intensified?

The questioner : Yes. He is asked for the green hands. Does he respond to it? Yes.

The Shaykh : There is scholarly disagreement on this. Whether to intensify the oath or the ruling on its intensification is up to the judge, not the plaintiff. The second issue is whether it is intensified in every case, even in trivial matters like a dirham or the like, or whether it is not intensified except in major, significant matters? The correct view is that it is up to the judge and that it is not intensified except in major, significant matters, because the generality of the saying of the Messenger (peace and blessings be upon him), "The oath is upon the one who denies," implies that it is not intensified.
