Musnad Ahmad 3857

It was narrated that Abul Ahwas said: ‘Abdullah (رضي الله عنه) said: The Messenger of Allah (ﷺ) said: “I disavow the friendship of anyone who claims l am his close friend. If I were to have taken a close friend (khaleel) I would have taken Ibn Abu Quhafah (i.e., Abu Bakr) as a close friend, but your companion (meaning himself) is the close friend (khaleel) of Allah."
