Duty of Guardian of the Dead Person when He is in Doubt about Dead Person's Indebting
Issue No. 1439- If the legal guardian of a dead individual does not know whether the dead person had qaḍā fasts or not, it will not be obligatory on him to perform qaḍā fast. However, if he knows that he has some qaḍā fasts due from him but does not know their amount, then he should perform the number of qaḍā fasts that he is certain about, and he is not obliged more.
