Musnad Abu Ya'la al-Mawsili 117:48

Hadbata narrated to us, Hammad narrated to us, from Thabit, from Anas, that the Prophet (peace and blessings of Allah be upon him), when he arrived at Badr, gestured with his hand toward the ground and said: "This is the place of death of so-and-so." By Allah, not one of them moved away from his place of death.
