Arabic (Original)
حَدَّثَنَا يَحْيَى عَنْ عُبَيْدِ اللَّهِ عَنْ نَافِعٍ عَنِ ابْنِ عُمَرَ عَنْ النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ قَالَ إِذَا نَصَحَ الْعَبْدُ لِسَيِّدِهِ وَأَحْسَنَ عِبَادَةَ رَبِّهِ لَهُ الْأَجْرُ مَرَّتَيْنِ.
English Translation
Yahya narrated to us, from 'Ubaydullah, from Nafi', from Ibn 'Umar, from the Prophet, peace and blessings be upon him, who said: "When a slave is sincere in service to his master and does well in worshipping his Lord, he has a double reward."
