Musnad Abu Ya'la al-Mawsili 129:80

'Abd al-A'la ibn Hammad al-Narsi narrated to us, Mu'tamir narrated to us, he said: I heard Humayd narrating from Anas ibn Malik, from the Prophet, peace and blessings of Allah be upon him, who said: "There is no servant who dies and has with Allah goodness, who would love to return to the world, and have the world and what is in it, except for the martyr. Because of what he sees of the virtue of martyrdom, he would love to return to the world so that he may be killed again."
