Musnad Abu Ya'la al-Mawsili 131:2

Dāwūd ibn ‘Amr narrated to us, ‘Abd Allāh ibn Idrīs narrated to us, he said: I heard Mukhtār ibn Fulful—and he was the most tender of the narrators who would narrate, and his eyes would shed tears—mentioning on the authority of Anas ibn Mālik: A man said to the Messenger of Allāh, "O best of creation!" The Messenger of Allāh, peace and blessings of Allāh be upon him, said, "That is Ibrāhīm, peace be upon him."
