'Abu Hurairah narrated that the Messenger of Allah said:
حَدَّثَنَا ابْنُ أَبِي عُمَرَ ، حَدَّثَنَا سُفْيَانُ ، عَنِ الأَعْمَشِ ، عَنْ أَبِي صَالِحٍ ، عَنْ أَبِي هُرَيْرَةَ ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم قَالَ " نِعِمَّا لأَحَدِهِمْ أَنْ يُطِيعَ رَبَّهُ وَيُؤَدِّيَ حَقَّ سَيِّدِهِ " يَعْنِي الْمَمْلُوكَ . وَقَالَ كَعْبٌ صَدَقَ اللَّهُ وَرَسُولُهُ . وَفِي الْبَابِ عَنْ أَبِي مُوسَى وَابْنِ عُمَرَ . قَالَ أَبُو عِيسَى هَذَا حَدِيثٌ حَسَنٌ صَحِيحٌ .
"How wonderful it is for one of them that he obeys Allah and fulfills the rights of his master." Meaning the slave. And Ka'b said: "Allah and His Messenger spoke the truth."
