وَحَدَّثَنَا مُحَمَّدُ بْنُ رَافِعٍ، حَدَّثَنَا عَبْدُ الرَّزَّاقِ، حَدَّثَنَا مَعْمَرٌ، عَنْ هَمَّامِ بْنِ مُنَبِّهٍ، قَالَ هَذَا مَا حَدَّثَنَا أَبُو هُرَيْرَةَ، عَنْ رَسُولِ اللَّهِ صلى الله عليه وسلم فَذَكَرَ أَحَادِيثَ مِنْهَا وَقَالَ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم " نِعِمَّا لِلْمَمْلُوكِ أَنْ يُتَوَفَّى يُحْسِنُ عِبَادَةَ اللَّهِ وَصَحَابَةَ سَيِّدِهِ نِعِمَّا لَهُ " .
Abu Huraira reported Allah's Messenger (ﷺ) as saying:
It is good for a slave that he worships Allah well, and serves his master (well). It is good for him.
