Musnad Ahmad 33:25

'Abd al-Razzaq narrated to us, Sufyan informed us—and Abu Nu'aym narrated to us, Sufyan narrated to us—from Abu al-Zubayr, from Jabir ibn 'Abd Allah, who said: "I saw the Prophet, peace and blessings of Allah be upon him, praying in a single garment, wrapping himself in it." Abu al-Zubayr said: "And I saw Jabir praying in a single garment, wrapping himself in it." Abu Nu'aym said in his narration: "And I saw Jabir praying," and he did not name Abu al-Zubayr.
