Manumission of Slaves
كتاب العتق
Chapter 19: The slave is a guardian of the property of his master.
The Prophet (peace and blessings of Allah Allaah be upon him) attributed the money to the Sayyid.
Narrated `Abdullah bin `Umar
That he heard Allah's Messenger (ﷺ) saying, "Everyone of you is a guardian and is responsible for his charge; the ruler is a guardian and is responsible for his subjects; the man is a guardian in his family and responsible for his charges; a woman is a guardian of her husband's house and responsible for her charges; and the servant is a guardian of his master's property and is responsible for his charge." I definitely heard the above from the Prophet (ﷺ) and think that the Prophet (ﷺ) also said, "A man is a guardian of his father's property and responsible for his charges; so everyone of you is a guardian and responsible for his charges."
Chapter 20: If somebody beats a slave, he should avoid his face.
Narrated Abu Huraira
The Prophet (ﷺ) said, "If somebody fights (or beats somebody) then he should avoid the face."
