حَدَّثَنِي مَالِكٌ، عَنْ نَافِعٍ، عَنْ عَبْدِ اللَّهِ بْنِ عُمَرَ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم قَالَ الْعَبْدُ إِذَا نَصَحَ لِسَيِّدِهِ وَأَحْسَنَ عِبَادَةَ اللَّهِ فَلَهُ أَجْرُهُ مَرَّتَيْنِ .
Malik related to me from Nafi from Abdullah ibn Umar that the Messenger of Allah, (ﷺ), said, "When a slave gives good counsel to his master and worships Allah correctly, he has his reward twice over. "
