Al-Adab al-Mufrad

The slave is a guardian

Ibn 'Umar reported that the Messenger of Allah, (ﷺ), said, "All of you are shepherds and each of you is responsible for his flock. The amir of a people is a shepherd and he is responsible for his flock. A man is the shepherd of the people of his house and he is responsible for his flock. A man's slave is the shepherd of his master's property and he is responsible for it. Each of you is a shepherd and each of you is responsible for his flock."

The slave is a guardian

Abu Hurayra said, "When a slave obeys his master, he has obeyed Allah Almighty. When he rebels against his master, he rebels against Allah Almighty."

The person who wished he were a slave

Abu Hurayra reported that the Messenger of Allah, (ﷺ), said, "When the Muslim slave performs the due of Allah and the due of his master, he will have two rewards."

Do not say "'abdi" (my slave)

Abu Hurayra reported that the Prophet, (ﷺ), 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).'"

Does one say "my master (sayyidi)"?

Abu Hurayra reported that the Prophet, (ﷺ), said, "None of you should say 'my slave ('abdi or amati)' and a slave should not say, 'my lord (rabbi or rabbati)'. They should say, 'my boy' or 'my girl' (fatayi and fatati) and 'my master' or 'mistress' (sayyidi and sayyidati)'. All of you are slaves, and the Lord is Allah, Almighty and Exalted."

Does one say "my master (sayyidi)"?

Mutarrif reported that his father said, "I went in the delegation of the Banu 'Amir to the Prophet, (ﷺ). They said, 'You are our master.' He said, 'The Master is Allah.' They said, 'The best of us in excellence and the greatest of us in generosity.' He said, 'Say what you like, but do not let Shaytan provoke you.'"
