Is the testimony of an heir for the deceased permissible regarding financial matters when the heir might inherit the property?
General Chapter
Al-Mughni
Book of Testimonies
Primary text
The testimony of an heir for the deceased is accepted concerning matters where no right currently exists for the heir, even if a right is only probable in the future, such as testifying for a woman one might marry, or for a creditor when the debtor's solvency is uncertain. The prohibition only applies when the witness immediately gains a benefit at the time of testimony.
Supporting text
The prohibition against accepting testimony regarding defamation before healing is based on the immediate possibility that the death results, obligating the heir to pay *diyah* immediately, thus establishing a right for the heir at the inception of the testimony.
