And I know of no disagreement regarding this. Ibn al-Mundhir said: It is established that the Messenger of Allah (may Allah bless him and grant him peace) performed ghusl because of (13) unconsciousness (14). They unanimously agreed that it is not mandatory, and because the loss of consciousness itself does not necessitate ghusl, while the occurrence of ejaculation is doubtful. Thus, we do not abandon certainty for doubt. If, however, it is certain for both of them that ejaculation occurred, then ghusl is mandatory upon them, because it would be due to a wet dream, thus entering into the category of the aforementioned obligations. It is recommended to perform ghusl for all those instances for which we denied the obligation of ghusl, due to the existence of evidence indicating that the Prophet (may Allah bless him and grant him peace) did so, and to exit from the disagreement.

All of this is the view of Malik, al-Shafi'i, and the scholars of opinion (Ahl al-Ra'y), and no disagreement is preserved from others. It was narrated that Abu Hurayra met the Messenger of Allah (may Allah bless him and grant him peace) on one of the paths of Medina while he was in a state of janaba. He said: I slipped away from him and performed ghusl, then I returned. He (the Prophet) said: "Where were you, O Abu Hurayra?" He said: O Messenger of Allah, I was in a state of janaba, and I disliked sitting with you while I was in a state of impurity. He said: "Subhan Allah! Indeed, the believer does not become filthy" (Agreed upon) (1). It is also narrated that one of the wives of the Prophet (may Allah bless him and grant him peace) brought him a bowl to perform wudu from it. A woman said: I dipped my hands into it while I was in a state of janaba. He said: "The water does not become impure due to janaba" (2). And he said to 'A'isha: "Hand me the khumra (prayer mat)...
