Abdallah b. ‘Amr told that he asked God’s Messenger to tell him about jihad and he replied,“If you fight with endurance, ‘Abdallah b. ‘Amr, seeking from God your reward, God will resurrect you showing endurance and seeking your reward from Him, but if you fight for vain show seeking to acquire much God will resurrect you making a vain show and seeking to acquire much. In whatever state you fight or are killed, ‘Abdallah b. ‘Amr, in that state God will resurrect you." Abu Dawud transmitted it.
