Musnad Ahmad 23560

Translation

✧ Abu Ayyub raided the Byzantines and fell ill. When he was at the point of death, he said: "When I die, carry me. When you meet the enemy in battle, bury me under your feet. I will tell you a hadith I heard from the Messenger of Allah ﷺ; were it not for this state of mine, I would not have told it to you. I heard the Messenger of Allah ﷺ say: 'Whoever dies without associating anything with Allah will enter Paradise.'"
