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. (Using translation from Muslim 2249a)
عَنِ النَّبِيِّ ﷺ قَالَ لَا يَقُولَنَّ أَحَدُكُمْ عَبْدِي وَأَمَتِي كُلُّكُمْ عَبِيدُ اللهِ وَكُلُّ نِسَائِكُمْ إِمَاءُ اللهِ وَلَكِنْ لِيَقُلْ غُلَامِي وَجَارِيَتِي وَفَتَايَ وَفَتَاتِي
