Musnad Ahmad 32:1219

Rawh and ‘Affan narrated to us, they said: Hammad narrated to us, from Thabit, from Anas, who said: The Messenger of Allah (peace and blessings of Allah be upon him) said: "A man from the people of Paradise will be brought, and it will be said to him: 'O son of Adam, how did you find your dwelling?' He will say: 'O my Lord, it is the best dwelling.' He will say: 'Ask and wish.' He will say: 'I do not ask or wish for anything except that You return me to the world so that I may be killed in Your cause ten times,' because of what he sees of the virtue of martyrdom. And a man from the people of the Fire will be brought, and it will be said to him: 'O son of Adam, how did you find your dwelling?' He will say: 'O my Lord, it is the worst dwelling.' He will say to him: 'Would you ransom yourself from it with the earth full of gold?' He will say: 'Yes, O my Lord.' He will say: 'You have lied; I asked you for less than that and easier, but you did not do it.' Then he will be returned to the Fire."
