عَنْ أَبِي هُرَيْرَةَ قَالَ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: «مَا لِأَحَدٍ عِنْدَنَا يَدٌ إِلَّا وَقَدْ كَافَيْنَاهُ مَا خَلَا أَبَا بَكْرٍ فَإِنَّ لَهُ عِنْدَنَا يَدًا يُكَافِيهِ اللَّهُ بهَا يومَ الْقِيَامَة وَمَا نَفَعَنِي مَالٌ قَطُّ مَا نَفَعَنِي مَالُ أَبِي بَكْرٍ وَلَوْ كُنْتُ مُتَّخِذًا خَلِيلًا لَاتَّخَذْتُ أَبَا بَكْرٍ خَلِيلًا أَلَا وَإِنَّ صَاحِبَكُمْ خَلِيلُ اللَّهِ» . رَوَاهُ التِّرْمِذِيّ

Abu Huraira reported God’s messenger as saying, “No one has helped me without my making it up to him except Abu Bakr, for he has given me help which God will make up to him on the day of resurrection. No one’s property has benefited me to the extent of Abu Bakr’s, and if I were taking a friend I would take Abu Bakr as a friend, but your companion is God’s friend.” Tirmidhi transmitted it.
