Manumission of Slaves
49/16. Chapter:
A slave who worships his Lord and he is also honest and faithful to his master
Sahih Bukhari
حَدَّثَنَا عَبْدُ اللَّهِ بْنُ مَسْلَمَةَ، عَنْ مَالِكٍ، عَنْ نَافِعٍ، عَنِ ابْنِ عُمَرَ ـ رضى الله عنهما ـ أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم قَالَ " الْعَبْدُ إِذَا نَصَحَ سَيِّدَهُ وَأَحْسَنَ عِبَادَةَ رَبِّهِ كَانَ لَهُ أَجْرُهُ مَرَّتَيْنِ ".
Narrated Ibn `Umar: Allah's Messenger (ﷺ) said, "If a slave is honest and faithful to his master and worships his Lord (Allah) in a perfect manner, he will get a double reward."
