The Prophet ﷺ said, "If a slave serves his Saiyid (i.e. master) sincerely and worships his Lord (Allah) perfectly, he will get a double reward."  

عَنِ النَّبِيِّ ﷺ قَالَ إِذَا نَصَحَ الْعَبْدُ سَيِّدَهُ وَأَحْسَنَ عِبَادَةَ رَبِّهِ كَانَ لَهُ أَجْرُهُ مَرَّتَيْنِ  

The Prophet ﷺ said, "The Mamluk (slave) who worships his Lord in a perfect manner, and is dutiful, sincere and obedient to his Saiyid (master), will get a double reward."  

عَنِ النَّبِيِّ ﷺ قَالَ الْمَمْلُوكُ الَّذِي يُحْسِنُ عِبَادَةَ رَبِّهِ وَيُؤَدِّي إِلَى سَيِّدِهِ الَّذِي لَهُ عَلَيْهِ مِنَ الْحَقِّ وَالنَّصِيحَةِ وَالطَّاعَةِ لَهُ أَجْرَانِ  

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).  

أَنَّهُ سَمِعَ أَبَا هُرَيْرَةَ ؓ يُحَدِّثُ عَنِ النَّبِيِّ ﷺ أَنَّهُ قَالَ لاَ يَقُلْ أَحَدُكُمْ أَطْعِمْ رَبَّكَ وَضِّئْ رَبَّكَ اسْقِ رَبَّكَ وَلْيَقُلْ سَيِّدِي مَوْلاَىَ وَلاَ يَقُلْ أَحَدُكُمْ عَبْدِي أَمَتِي وَلْيَقُلْ فَتَاىَ وَفَتَاتِي وَغُلاَمِي  

The Prophet ﷺ said, "If one manumits his share of a common slave (Abd), and he has money sufficient to free the remaining portion of the price of the slave (justly estimated), then he should free the slave completely by paying the rest of his price; otherwise the slave is freed partly. "  

قَالَ النَّبِيُّ ﷺ مَنْ أَعْتَقَ نَصِيبًا لَهُ مِنَ الْعَبْدِ فَكَانَ لَهُ مِنَ الْمَالِ مَا يَبْلُغُ قِيمَتَهُ يُقَوَّمُ عَلَيْهِ قِيمَةَ عَدْلٍ وَأُعْتِقَ مِنْ مَالِهِ وَإِلاَّ فَقَدْ عَتَقَ مِنْهُ  

Messenger of Allah ﷺ said, "Everyone of you is a guardian and is responsible for his charges. The ruler who has authority over people, is a guardian and is responsible for them, a man is a guardian of his family and is responsible for them; a woman is a guardian of her husband's house and children and is responsible for them; a slave ('Abu) is a guardian of his master's property and is responsible for it; so all of you are guardians and are responsible for your charges."  

أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ كُلُّكُمْ رَاعٍ فَمَسْئُولٌ عَنْ رَعِيَّتِهِ فَالأَمِيرُ الَّذِي عَلَى النَّاسِ رَاعٍ وَهْوَ مَسْئُولٌ عَنْهُمْ وَالرَّجُلُ رَاعٍ عَلَى أَهْلِ بَيْتِهِ وَهْوَ مَسْئُولٌ عَنْهُمْ وَالْمَرْأَةُ رَاعِيَةٌ عَلَى بَيْتِ بَعْلِهَا وَوَلَدِهِ وَهْىَ مَسْئُولَةٌ عَنْهُمْ وَالْعَبْدُ رَاعٍ عَلَى مَالِ سَيِّدِهِ وَهْوَ مَسْئُولٌ عَنْهُ أَلاَ فَكُلُّكُمْ رَاعٍ وَكُلُّكُمْ مَسْئُولٌ عَنْ رَعِيَّتِهِ  

The Prophet ﷺ said, "If a slave-girl (Ama) commits illegal sexual intercourse, scourge her; if she does it again, scourge her again; if she repeats it, scourge her again." The narrator added that on the third or the fourth offense, the Prophet ﷺ said, "Sell her even for a hair rope."  

عَنِ النَّبِيِّ ﷺ قَالَ إِذَا زَنَتِ الأَمَةُ فَاجْلِدُوهَا ثُمَّ إِذَا زَنَتْ فَاجْلِدُوهَا ثُمَّ إِذَا زَنَتْ فَاجْلِدُوهَا فِي الثَّالِثَةِ أَوِ الرَّابِعَةِ بِيعُوهَا وَلَوْ بِضَفِيرٍ
