Abu Hurayra reported that the Prophet, may Allah bless him and grant him peace, said, "None of you should say, 'My slave ('abdi)' or 'my slavegirl (amati)' All of you are slaves of Allah and all of your women are slaves of Allah. Rather you should say, 'My boy (ghulami)', my slavegirl (jariyyati)', 'my lad (fatayi)' or 'my girl (fatati).'"  

عَنِ النَّبِيِّ ﷺ قَالَ لاَ يَقُلْ أَحَدُكُمْ عَبْدِي أَمَتِي كُلُّكُمْ عَبِيدُ اللهِ وَكُلُّ نِسَائِكُمْ إِمَاءُ اللهِ وَلْيَقُلْ غُلاَمِي جَارِيَتِي وَفَتَايَ وَفَتَاتِي
