Abu Huraira:
The Prophet (ﷺ) said, "You should not say, 'Feed your lord (Rabbaka), help your lord in performing
ablution, or give water to your lord, but should say, 'my master (e.g. Feed your master instead of lord
etc.) (Saiyidi), or my guardian (Maulai), and one should not say, my slave (Abdi), or my girl-slave
(Amati), but should say, my lad (Fatai), my lass (Fatati), and 'my boy (Ghulami).
