Musnad Ahmad 604:1

Sufyan informed us, Mahdi ibn Ja'far al-Ramli narrated to us, Abu al-Walid Rudayh ibn 'Atiyyah narrated to us, from Ibrahim ibn Abi 'Ablah, who said: I saw Abu Ayyub al-Ansari—and he is Ibn Abi Haram al-Ansari—and he informed me: "That he prayed with the Messenger of Allah, may Allah bless him and grant him peace, facing both qiblahs, while he was wearing a dusty-colored silk cloak."
