Arabic (Original)
حَدَّثَنَا مُحَمَّدُ بْنُ عُبَيْدٍ حَدَّثَنَا عُبَيْدُ اللَّهِ عَنْ نَافِعٍ عَنِ ابْنِ عُمَرَ أَنَّ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ قَالَ إِذَا نَصَحَ الْعَبْدُ لِسَيِّدِهِ وَأَحْسَنَ عِبَادَةَ رَبِّهِ كَانَ لَهُ مِنْ الْأَجْرِ مَرَّتَيْنِ.

Muhammad ibn 'Ubayd told us: 'Ubaydullah told us, from Nafi', from Ibn 'Umar, that the Messenger of Allah, peace and blessings be upon him, said: "When a slave is sincere to his master and does well in the worship of his Lord, he will have a double reward."
