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.
