'Umar bin Al-Khattab (May Allah be pleased with him) reported: I sought permission of the Prophet (ﷺ) 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 (ﷺ) said, "Include us, my brother, in your supplications." .
