From Sahih Bukhari (Hadith 3398):
Narrated Abu Sa`id:The Prophet (ﷺ) said, 'People will be struck unconscious on the Day of Resurrection and I will be the first to regain consciousness, and behold! There I will see Moses holding one of the pillars of Allah's Throne. I will wonder whether he has become conscious before me, or if he has been exempted because of his unconsciousness at the Tur (mountain) which he received (on the earth)
