Arabic (Original)
حَدَّثَنَا ابْنُ نُمَيْرٍ 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 الْأَجْرُ مَرَّتَيْنِ.

Ibn Numayr told us; Ubaydullah told us, from Nafi', from Ibn Umar: that the Messenger of Allah, peace and blessings be upon him, said: "When a servant is sincere to his master and worships his Lord well, he will have a double reward."
