THE OBEDIENCE OF A BELIEVING SERVANT H 1393 "A servant who worships his Sustainer well and discharges his obligations diligently and obediently to his master will have a double reward." R 1393 Bukhari with a chain up to Abu Musa Ash'ari who related that the Messenger of Allah, praise and peace be upon him, said this.
1364- عن أَبي موسى الأشعري رضي الله عنه قَالَ : قَالَ رسول الله صلى الله عليه وآله وسلم : "المَمْلُوكُ الَّذِي يُحْسِنُ عِبَادَةَ رَبِّهِ ، وَيُؤَدِّي إِلَى سَيِّدِهِ الَّذِي عَلَيْهِ مِنَ الحَقِّ ، وَالنَّصِيحَةِ ، وَالطَّاعَةِ ، لهُ أجْرَانِ" رواه البخاري .
