وَعَنْ أَبِي سَعِيدٍ الْخُدْرِيِّ قَالَ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: «مَا مِنْ نَبِيٍّ إِلَّا وَلَهُ وَزِيرَانِ مِنْ أَهْلِ السَّمَاءِ وَوَزِيرَانِ مِنْ أَهْلِ الْأَرْضِ فَأَمَّا وَزِيرَايَ مِنْ أَهْلِ السَّمَاءِ فَجِبْرِيلُ وَمِيكَائِيلُ وَأَمَّا وَزِيرَايَ مِنْ أَهْلِ الْأَرْضِ فَأَبُو بَكْرٍ وَعُمَرُ» . رَوَاهُ التِّرْمِذِيُّ

Abu Sa’id al-Khudri reported God’s messenger as saying. “There is no prophet who does not have two wazirs from the inhabitants of heaven and two from the inhabitants of the earth. My two wazirs from the inhabitants of heaven are Gabriel and Michael, and my two wazirs from the inhabitants of the earth are Abu Bakr and `Umar.” Tirmidhi transmitted it, saying this is a hasan gharib tradition.
