11) باب ثَوَابِ الْعَبْدِ وَأَجْرِهِ إِذَا نَصَحَ لِسَيِّدِهِ وَأَحْسَنَ عِبَادَةَ اللَّهِ ‏‏

وَحَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ، وَأَبُو كُرَيْبٍ قَالاَ حَدَّثَنَا أَبُو مُعَاوِيَةَ، عَنِ الأَعْمَشِ، عَنْ أَبِي صَالِحٍ، عَنْ أَبِي هُرَيْرَةَ، قَالَ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم ‏‏ ‏.‏ قَالَ فَحَدَّثْتُهَا كَعْبًا فَقَالَ كَعْبٌ لَيْسَ عَلَيْهِ حِسَابٌ وَلاَ عَلَى مُؤْمِنٍ مُزْهِدٍ ‏.‏ "‏ إِذَا أَدَّى الْعَبْدُ حَقَّ اللَّهِ وَحَقَّ مَوَالِيهِ كَانَ لَهُ أَجْرَانِ ‏"
