Is the loss of reason a nullifier or a place where nullification is likely?

Question : But is it a nullifier or a place where nullification is likely?

Answer : There is a difference of opinion among the scholars. It is strange that the scholars have many views on sleep; there are eight schools of thought among them. Some say it nullifies, some say it does not, some do not distinguish, and some do distinguish. But let us look at it. When a person’s reason is completely lost...
The loss of reason is a strong indication, yes, because one may pass wind without being aware of it. When the cause is widespread and cannot be controlled, its effect is established by the slightest doubt or the slightest cause. Therefore, we say that as long as the cause for sleep being a nullifier is that it is a place where ritual impurity is likely, the ruling should be applied accordingly, simply upon the loss of reason by sleep or otherwise. Some scholars said that sleep itself is not a nullifier of the ablution; sleep itself is not a nullifier of the ablution, but it is a place where nullification is likely. Accordingly, if it is more likely in your mind that you are still in a state of purity, then you are pure; otherwise, you are not. The loss of reason by insanity, fainting, or intoxication is, in reality, a final loss. Accordingly, whether it is brief or prolonged, it is a nullifier. So if a man, may Allah protect us, has a seizure and then wakes up from the seizure, he must perform ablution. Likewise, if he becomes intoxicated, or if he falls from something and faints, he must perform ablution. This is different from sleep, which is not like these things. For this reason, it differs from these things in that a brief instance of it does not nullify. The loss of reason is like the loosening of the stopper; when the eyes sleep, the stopper is loosened. So there is also evidence and reasoning in this. Is anything excluded from that, O Shaybah? Is anything excluded from the loss of reason?
The insane person. In the name of Allah, the Most Gracious, the Most Merciful. The loss of reason is a nullifier of the ablution, as you have heard from the evidence and the reasoning. It is not a point of agreement among the scholars, but rather a point of disagreement among the scholars. However, the stronger opinion is that it is a nullifier, based on the wording of the hadith of Safwan ibn 'Uasal, and because the reasoning we referred to is strong.
