Musnad Ahmad 31:856

Rawh narrated to us, Awf narrated to us, from Abu Nadrah, from Abu Sa’id al-Khudri, from the Prophet, peace and blessings of Allah be upon him, who said: "A group will emerge from the Fire, having become charcoal. It will be said: 'Spread them out in Paradise, and sprinkle water upon them.' They will then sprout, just as a seed sprouts in the silt of a flood." A man from the people said: "It is as if you were a desert dweller, O Messenger of Allah."
