If a person falls unconscious before ‘Arafah, then he is carried to ‘Arafah on the day of ‘Arafah when he is unconscious, is his Hajj valid even if he is not aware?.
The scholars -- may Allah have mercy on them -- have stated that the standing in ‘Arafah of one who is unconscious is valid. If a person falls unconscious before dawn breaks on the day of ‘Arafah and does not wake up until after dawn on the day of Sacrifice, and he is in ‘Arafah and has stood or stayed in ‘Arafah, then his Hajj is valid.
