Musnad Ahmad 33:727

Yunus and ‘Affan narrated to us, they said: Hammad narrated to us, from Abu al-Zubayr, from Jabir, who said: "I saw the Messenger of Allah, may Allah bless him and grant him peace, praying in a single garment, wrapping himself in it." ‘Affan said: "He crossed its two ends over his shoulders."
