Musnad Ahmad 4138

It was narrated that 'Abdullah (رضي الله عنه) said: The Messenger of Allah (ﷺ) passed by me when I was praying and said: "Ask, you will be given, O son of Umm ‘Abd,” ‘Umar said: Abu Bakr and I raced and Abu Bakr beat me to him. We never competed with Abu Bakr in anything good but Abu Bakr beat me to it. He ('Abdullah) said: Part of my supplication that I almost never omit to say is: O Allah, I ask You for blessing that never ends and joy that never ceases and to accompany the Prophet Muhammad (ﷺ) in the highest part of Paradise, the Paradise of eternity.
