Arabic (Original)
حَدَّثَنَا يَحْيَى عَنْ عُبَيْدِ اللَّهِ وَمُحَمَّدُ بْنُ عُبَيْدٍ قَالَ حَدَّثَنَا عُبَيْدُ اللَّهِ عَنْ نَافِعٍ عَنِ ابْنِ عُمَرَ عَنْ النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ الْعَبْدُ إِذَا أَحْسَنَ عِبَادَةَ رَبِّهِ تَبَارَكَ وَتَعَالَى وَنَصَحَ لِسَيِّدِهِ كَانَ لَهُ الْأَجْرُ مَرَّتَيْنِ.

Yahya narrated to us, from 'Ubaydullah, and Muhammad ibn 'Ubayd said: 'Ubaydullah narrated to us, from Nafi', from Ibn 'Umar, from the Prophet, peace and blessings be upon him: "When a slave does well in worshipping his Lord, Blessed and Exalted, and is sincere in service to his master, he has a double reward."
