Is the testimony of an interested party who benefits directly from their testimony valid?
General Chapter
Al-Mughni
Book of Testimonies
Primary text
The testimony of one who benefits directly from it, drawing advantage to themselves, is invalid. This includes creditors testifying for an insolvent person regarding a debt or asset, because if the debt or asset is established, their rights attach to it. This differs from creditors testifying for a living person not under receivership, where their testimony is accepted because their right pertains to the debtor's liability, not their assets.
Supporting text
If the insolvent person is poor, the claim against them is suspended. If creditors testify to an asset belonging to him, they gain the ability to claim it upon his recovery, but this future potential benefit does not invalidate the testimony, as the claim is established by his solvency or admission, not merely by their testimony.
