Abu Huraira reported Allah's Messenger (ﷺ) as saying
None of you should say: My bondman and my slave-girl, for all of you are the bondmen of Allah, and all your women are the slave-girls of Allah; but say: My servant, my girl, and my young man and my young girl.
Abu Huraira reported Allah's Messenger (ﷺ) as saying
None of you should say: My bondman, for all of you are the bondmen of Allah, but say: My young man, and the servant should not say: My Lord, but should say: My chief.
This hadith has been reported on the authority of al-A'mash with the same chain of transmitters , and the words are that the servant should not say to his chief
My Lord , and Abu Mu'awiya made an addition : " For it is Allah , the Exalted and Glorious , Who is your Lord."
Abu Huraira reported Allah's Messenger (ﷺ) so many ahadith and one of them is this that Allah's Messenger (ﷺ) said
None of you should say : Supply drink to your lord , feed your lord , help your lord in performing ablution , and none of you should say : My Lord. He should say : My chief , my patron ; and none of you should say : My bondman , my slave-girl , but simply say : My boy , my girl , my servant.
