Musnad Abu Ya'la al-Mawsili 150:68

Muhammad ibn Abdullah ibn Numayr narrated to us, Yunus ibn Bukayr narrated to us, Hisham ibn Urwah narrated to us, from his father, from Aisha, who said: There was no one with the Prophet, may Allah bless him and grant him peace, when he migrated from Makkah to Madinah except Abu Bakr, Amir ibn Fuhayrah, and a man from Banu al-Dil who was a polytheist and was their guide.
