Sahih Bukhari | Volume 8 | Hadith Number 525

Narrated by Abu Huraira
The Prophet said, "The people will fall down unconscious at the time when they should fall down (i.e., on the Day of Resurrection), and then I will be the first man to get up, and behold, Moses will be there holding (Allah's) Throne. I will not know whether he has been amongst those who have fallen unconscious."
