It is not necessary to perform the qaḍāʾ prayers of a deceased person in the order they became qaḍāʾ except for the prayers that must be performed in a particular order when they are performed within their prescribed time, such as ẓuhr and ʿaṣr prayers, and maghrib and ʿishāʾ prayers, of the same day, as was mentioned previously.
However, if someone is hired to act according to the fatwa of the deceased’s marjaʿ[5] or according to the marjaʿ of the deceased’s guardian (walī),[6] and that marjaʿ considers it necessary to observe the order, then one must observe the order.
