The Book of Jihad
The Merit of the Dutiful Slave
عَنِ ابْنِ عُمَرَ رَضِيَ اللَّه عَنْهُمَا أَنَّ رَسُولَ اللَّهِ صَلَّى اللَّه عَلَيْهِ وَسَلَّمَ قَالَ: إِنَّ الْعَبْدَ إِذَا نَصَحَ لِسَيِّدِهِ، وَأَحْسَنَ عِبَادَةَ اللَّهِ، فَلَهُ أَجْرُهُ مَرَّتَيْنِ ((مُتَّفَقٌ عَلَيْهِ))
Ibn 'Umar (May Allah be pleased with them) reported: I heard the Messenger of Allah (ﷺ) saying, "When a slave is sincere to his master and worships Allah well, He will have a double reward." [Al-Bukhari and Muslim].
