The slave should not say Rabbi or Rabbati (My lord, My lady)

Narrated AbuHurayrah:

The Prophet ﷺ said: None of you must say: "My slave" (abdi) and "My slave-woman" (amati), and a slave must not say: "My lord" (rabbi or rabbati). The master (of a slave) should say: "My young man" (fataya) and "My young woman" (fatati), and a slave should say "My master" (sayyidi) and "My mistress" (sayyidati), for you are all (Allah's slave and the Lord is Allah, Most High.

حَدَّثَنَا مُوسَى بْنُ إِسْمَاعِيلَ، حَدَّثَنَا حَمَّادٌ، عَنْ أَيُّوبَ، وَحَبِيبِ بْنِ الشَّهِيدِ، وَهِشَامٍ، عَنْ مُحَمَّدٍ، عَنْ أَبِي هُرَيْرَةَ، أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ " لاَ يَقُولَنَّ أَحَدُكُمْ عَبْدِي وَأَمَتِي وَلاَ يَقُولَنَّ الْمَمْلُوكُ رَبِّي وَرَبَّتِي وَلْيَقُلِ الْمَالِكُ فَتَاىَ وَفَتَاتِي وَلْيَقُلِ الْمَمْلُوكُ سَيِّدِي وَسَيِّدَتِي فَإِنَّكُمُ الْمَمْلُوكُونَ وَالرَّبُّ اللَّهُ عَزَّ وَجَلَّ " .

The tradition mentioned above has also been transmitted by Abu Hurairah through a different chain of narrators. This version does not mention the Prophet ﷺ i.e, it does not go back to him. It has :
He must say: “My master” (sayyidi) and “My patron” (mawlaya).

حَدَّثَنَا ابْنُ السَّرْحِ، أَخْبَرَنَا ابْنُ وَهْبٍ، قَالَ أَخْبَرَنِي عَمْرُو بْنُ الْحَارِثِ، أَنَّ أَبَا يُونُسَ، حَدَّثَهُ عَنْ أَبِي هُرَيْرَةَ، فِي هَذَا الْخَبَرِ وَلَمْ يَذْكُرِ النَّبِيَّ ﷺ قَالَ " وَلْيَقُلْ سَيِّدِي وَمَوْلاَىَ " .
