Q: What about the case of a patient who had been very ill that he was hallucinating and he couldn't have control over his mental thoughts. Does the patient have to pray in this state? If he does not, does he have to make up all these prayers?
A: if the person is sick and hallucinating then he's not required to pray since the one who is insane is not Mokallaf (should not) to pray. But in case he becomes insane at times (unconscious) and sane (conscious) at others, then he should pray when he is sane (conscious) .
