Chapter 11: The reward of a slave who is sincere towards his master and worships Allah properly
باب ثَوَابِ الْعَبْدِ وَأَجْرِهِ إِذَا نَصَحَ لِسَيِّدِهِ وَأَحْسَنَ عِبَادَةَ اللَّهِ
Sahih Muslim 1665 b
This hadith has been transmitted on the authority of Abu Tahir but with a slight variation of words.
وَحَدَّثَنِيهِ زُهَيْرُ بْنُ حَرْبٍ، حَدَّثَنَا أَبُو صَفْوَانَ الأُمَوِيُّ، أَخْبَرَنِي يُونُسُ، عَنِ ابْنِ شِهَابٍ، بِهَذَا الإِسْنَادِ وَلَمْ يَذْكُرْ بَلَغَنَا وَمَا بَعْدَهُ .
