حَدَّثَنَا عَلِيُّ بْنُ الْحَسَنِ الْكُوفِيُّ، حَدَّثَنَا مَحْبُوبُ بْنُ مُحْرِزٍ الْقَوَارِيرِيُّ، عَنْ دَاوُدَ بْنِ يَزِيدَ الأَوْدِيِّ، عَنْ أَبِيهِ، عَنْ أَبِي هُرَيْرَةَ، قَالَ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم ‏"‏ مَا لأَحَدٍ عِنْدَنَا يَدٌ إِلاَّ وَقَدْ كَافَيْنَاهُ مَا خَلاَ أَبَا بَكْرٍ فَإِنَّ لَهُ عِنْدَنَا يَدًا يُكَافِئُهُ اللَّهُ بِهَا يَوْمَ الْقِيَامَةِ وَمَا نَفَعَنِي مَالُ أَحَدٍ قَطُّ مَا نَفَعَنِي مَالُ أَبِي بَكْرٍ وَلَوْ كُنْتُ مُتَّخِذًا خَلِيلاً لاَتَّخَذْتُ أَبَا بَكْرٍ خَلِيلاً أَلاَ وَإِنَّ صَاحِبَكُمْ خَلِيلُ اللَّهِ ‏"‏ ‏.‏ قَالَ أَبُو عِيسَى هَذَا حَدِيثٌ حَسَنٌ غَرِيبٌ مِنْ هَذَا الْوَجْهِ ‏.‏

Narrated Abu Hurairah: that the Messenger of Allah (PBUH) said: "There is no favor due upon us from anyone, except that we have repaid him, with the exception of Abu Bakr. Verily upon us, there is a favor due to him, which Allah will repay him on the Day of Judgement. No one's wealth has benefited as Abu Bakr's wealth has benefited me. And if I were to take a Khalil, then I would have taken Abu Bakr as a Khalil, and indeed your companion is Allah's Khalil. Translation Not Available
