Musnad Abu Ya'la al-Mawsili 116:46

Ahmad narrated to us, Abu Dawud narrated to us, Shu'bah narrated to us, from Qatadah, who heard Anas bin Malik narrating from the Messenger of Allah (may Allah bless him and grant him peace), who said: "There is no servant who has goodness with Allah, and who would love to return to the world, except for the martyr. For he would love to return and be killed ten times, because of what he sees of the virtue of the honor."
