Are the heirs of the deceased required to pay a debt to a claimant who has no evidence to prove the validity of his claim other than verbal statements?

The resolution of dispute cases takes place in the Sharia (definition) courts. The general rule is that a debt claim against a deceased person should not be accepted without evidence or the acknowledgment of the heirs. If you were unaware of this debt and do not acknowledge it, you are not obligated to pay it from the estate unless there is evidence. However, if there are circumstantial indications supporting the claim, it is preferable to pay the amount, reconcile, or seek forgiveness; this is a precautionary measure for the deceased.
