Musnad Ahmad 33:427

Abu Ahmad narrated to us, Abd al-Hamid narrated to us, from Uqbah ibn Abd al-Rahman, from Jabir, who said: "We used to pray the Maghrib [prayer] with the Messenger of Allah, may Allah bless him and grant him peace, then we would return to [the dwellings of] Banu Salamah, and we could [still] see the landing spots of the arrows."
