HAKIM 4448:
from Bakr —
[Machine] "I heard the Messenger of Allah ﷺ saying, 'I have intended to send men to different regions to teach people the Sunnahs and obligations, just as 'Isa bin Maryam sent his disciples.' It was said to him, 'What about Abu Bakr and 'Umar?' He replied, 'I cannot do without them, as they are part of the religion, like hearing and sight are.'"
الحاكم ٤٤٤٨:
عن بكر —
سَمِعْتُ رَسُولَ اللَّهِ ﷺ يَقُولُ «لَقَدْ هَمَمْتُ أَنْ أَبْعَثَ إِلَى الْآفَاقِ رِجَالًا يُعَلِّمُونَ النَّاسَ السُّنَنَ وَالْفَرَائِضَ كَمَا بَعَثَ عِيسَى ابْنُ مَرْيَمَ الْحَوَارِيِّينَ» قِيلَ لَهُ فَأَيْنَ أَنْتَ مِنْ أَبِي بَكْرٍ وَعُمَرَ؟ قَالَ «إِنَّهُ لَا غِنًى بِي عَنْهُمَا إِنَّهُمَا مِنَ الدِّينِ كَالسَّمْعِ وَالْبَصَرِ»
