وَعَنْ عُمَرَ بْنِ الْخَطَّابِ رَضِيَ اللَّهُ عَنْهُ قَالَ: اسْتَأْذَنْتُ النَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ فِي الْعُمْرَةِ، فَأَذِنَ لِي، وَقَالَ: "لاَ تَنْسَنَا يَا أخي مِنْ دُعَائِكَ" فَقَالَ كَلِمَةً مَا يَسُرُّنِي أَنَّ لِي بِهَا الدُّنْيَا. وفي رواية قَالَ: "أَشْرِكْنَا يَا أخي فِي دُعَائِكَ". حَدِيث صَحِيح ((رَوَاهُ أَبُو دَاوُدَ، وَالتِّرْمِذِيُّ وَقَالَ: حَدِيث حَسَن صَحِيح)).
'Umar bin Al-Khattab (May Allah be pleased with him) reported: I sought permission of the Prophet (ﷺ) to perform 'Umrah. He granted me leave and said, "Dear brother! Do not forget us in your supplications". ('Umar added): This is something I would not exchange for the whole world. Another narration is: He (ﷺ) said, "Include us, my dear brother, in your supplications." [Abu Dawud and At-Tirmidhi, who categorized the Hadith as Hasan Sahih.].
