Musnad Ahmad 4062

It was narrated that ‘Abdullah (رضي الله عنه) said: "The Messenger of Allah (ﷺ) said: “Every Prophet has a close associate among the Prophets, and my close associate among them is my father and the close friend of my Lord (Ibraheem).” Then he recited: “Verily, among mankind who have the best claim to Ibraheem (Abraham) are those who followed him, and this Prophet (Muhammad (ﷺ)) and those who have believed (Muslims)." (Al 'Imran 3:68]
