It was narrated that 'Abdullah (رضي الله عنه) said:

The Messenger of Allah (ﷺ) passed by me when was praying and said: “Ask, you will be given, O son of Umm Abd." Abu Bakr andʻUmar (رضي الله عنهما) raced (to ask him about his supplication). ‘Umar said: I never competed with Abu Bakr in anything but he beat me to it. They asked him about what he had said, and he 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.
