Will a patient with Alzheimer's disease who comprehends nothing be rewarded or punished for his actions, and is his illness considered an atonement for him for which he will be rewarded?

Summary of the Fatwa for a patient with late-stage Alzheimer's: 1. Reward and Recompense: The reward for affliction and expiation of sins is written for him, which is an additional reward beyond patience and does not require action or intention. If he had a habit of performing good deeds before his illness, the reward for those deeds is written for him, based on the hadith: "When a servant falls ill or travels, the like of what he used to do when he was a resident and healthy is written for him." This reward is attained even with the absence of intellect, which entails the absence of patience; it is a favor from Allah Almighty.

2. Legal Rulings (Ahkam Taklifiyyah): There is no reward or punishment for him concerning actions related to the responsibility of accountable individuals, as the cause for accountability has been lifted from him.
