وعن عمر بن الخطاب رضي الله عنه
قال: استأذنت النبي صلى الله عليه وسلم الله عليه وسلم في العمرة، فأذن، وقال: «لا تنسانا يا أخي من دعائك«فقال كلمة ما يسرني أن لي بها الدنيا. وفي رواية قال: «أشركنا يا أخي في دعائك»
I sought permission of the Prophet (sallallahu alayhi wa sallam) to perform Umrah, and he granted me leave and said, “Brother, do not forget us in your supplications.” I would not exchange these words of his for the whole world. Another narration is: He (sallallahu alayhi wa sallam) said, “Include us, my brother, in your supplications.”.
