عَنِ ابْنِ عُمَرَ رَضِيَ اللَّهُ عَنْهُمَا عَنِ النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ قَالَ الْعَبْدُ إِذَا أَحْسَنَ عِبَادَةَ رَبِّهِ تَبَارَكَ وَتَعَالَى وَنَصَحَ لِسَيِّدِهِ كَانَ لَهُ أَجْرُهُ مَرَّتَيْنِ
Sayyiduna Abdullah bin Umar (may Allah be pleased with them both) narrates that the Noble Prophet (peace and blessings be upon him) said: When a slave worships his Lord in a good manner and is also sincere to his master, then he will have a double reward.
