Musnad Ahmad 31:296

Waki’ narrated to us, from Sufyan, from ‘Amr ibn Yahya, from his father, from Abu Sa’id al-Khudri, who said: The Messenger of Allah (peace and blessings of Allah be upon him) said: "Do not make distinctions between the prophets. I will be the first person for whom the earth will split open on the Day of Resurrection. I will then regain consciousness and find Musa holding onto one of the pillars of the Throne. I do not know if he was recompensed for the swoon at Mount Tur, or if he regained consciousness before me."
