One who frees his share in a slave

Isma'il bin Umayyah relates this statement of his grandfather: There was a slave whose name was Tahman, or perhaps Dhakwan. His grandfather freed his own share of him. That slave came to the Prophet (peace and blessings be upon him) and spoke to the Prophet (peace and blessings be upon him), and the Prophet (peace and blessings be upon him) said: "You are free in your neck, and you are a slave in your neck (that is, you are partly free and partly a slave)." The narrator says: So that slave kept serving his master until he died.
Imam Ahmad recorded this narration, and
this narration is mursal, and its narrators are thiqat (trustworthy).
Imam al-Tabarani recorded this narration and said: from Isma'il bin Umayyah, from his father, from his grandfather. He
recorded this narration by way of Abdullah bin Ahmad, from his father, with his chain; so it is possible that these words dropped out of my copy, namely that he narrated it from his father, from his grandfather. And Allah knows best.

Sayyiduna Abdullah bin Sinan al-Muzani (may Allah be pleased with him) narrates: The Prophet (peace and blessings be upon him) said: "A man may free as much of his slave as he wishes: if he wishes, he may free a third of him, and if he wishes, a quarter."
Imam al-Tabarani recorded this narration in al-Mu'jam al-Kabir and al-Mu'jam al-Awsat, and he states: "If he wishes, he may free a fifth; there is no compulsion (or coercion) between him and Allah Almighty." The chain of this narration contains a narrator, Muhammad bin Fada', who is da'if (weak).

Sayyiduna Jabir bin Abdullah (may Allah be pleased with him) narrates: A slave was owned by ten men. Nine of them freed (their respective shares), and the tenth refused to free his share. He said: "O Messenger of Allah! This is my standing." The Prophet (peace and blessings be upon him) said: "Your standing is in it."
Imam al-Tabarani recorded this narration in al-Mu'jam al-Awsat; its chain contains a narrator, Muhammad bin al-Fadl, who is matruk (abandoned).

Muhammad bin Umar bin Sa'id narrates: A slave was owned by ten men. They freed him, but one of them did not free him. He came to the Prophet (peace and blessings be upon him) so that he might have the Prophet (peace and blessings be upon him) intercede for him with that man. The Prophet (peace and blessings be upon him) spoke to that man about the slave, and the man presented his share to the Prophet (peace and blessings be upon him), and the Prophet (peace and blessings be upon him) freed the slave. That slave used to say: "I am the freed slave of the Prophet (peace and blessings be upon him)." His name was "Rafi' Abu al-Bahiyy".
Imam al-Tabarani recorded this narration; I do not know this narrator named Muhammad bin Umar; the remaining narrators of this narration are the narrators of the Sahih.

Sayyiduna Samurah (may Allah be pleased with him) relates from the Prophet (peace and blessings be upon him): A man from the tribe of Hudhayl freed his share (in a slave), and the Prophet (peace and blessings be upon him) said: "That slave will be counted as free, for Allah Almighty has no partner."
Imam Ahmad recorded this narration similar to the hadith before it, and these words of the narration are his; the narrators of this narration are the narrators of the Sahih.

Sa'id bin al-Musayyab narrates: We have preserved from thirty Companions, from the Prophet (peace and blessings be upon him), that he said: "Whoever frees his share in a slave will be liable (to the other owners) for the rest of his value."
Imam Ahmad recorded this narration; its chain contains a narrator, al-Hajjaj bin Artah, who is thiqah (trustworthy), but he is a mudallis (one who practises tadlis); the remaining narrators of this narration are the narrators of the Sahih.

Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both) narrates: The Prophet (peace and blessings be upon him) said: "Whoever frees (his) share in a slave will be liable from his own wealth to (the other partners) for their shares."
Imam al-Bazzar recorded this narration from Ibrahim bin Isma'il bin Yahya, from his father, and both of them are da'if (weak).

Sayyiduna Jabir bin Abdullah (may Allah be pleased with him) narrates: The Prophet (peace and blessings be upon him) said: "Whoever frees his share in a slave, it is binding on him to free the rest of him as well. If that person has no wealth, the slave will work to earn his value."
Imam al-Tabarani recorded this narration in al-Mu'jam al-Awsat; its chain contains a narrator, Muhammad bin Ishaq al-Marwazi, who is da'if (weak).

Sayyidah Aishah al-Siddiqah (may Allah be pleased with her) narrates: The Prophet (peace and blessings be upon him) said: "When a slave is jointly owned by several people and one of them frees him, the slave will be valued at the highest price; then he will pay his value as a liability (penalty), and the slave will be freed."
Imam al-Tabarani recorded this narration in al-Mu'jam al-Awsat; its chain contains a narrator, al-Muthanna bin al-Sabbah, who is da'if (weak), though he has also been declared trustworthy.

Sayyiduna Ubadah (may Allah be pleased with him) narrates: The Prophet (peace and blessings be upon him) said: "Whoever frees a share of a slave will be liable for the rest of him."

In one narration the words are: "Then it will be binding on him to have him freed completely, if that person has wealth."
Imam al-Tabarani recorded this narration, and the narrator Ishaq bin Yahya did not live in the time of Sayyiduna Ubadah (may Allah be pleased with him).

Sayyiduna Abdullah bin Mas'ud (may Allah be pleased with him) says: A slave was jointly owned by two men of the tribe of Juhaynah. One of the two freed him. That man came to the Prophet (peace and blessings be upon him), and the Prophet (peace and blessings be upon him) made him liable for it. That man had some goats, close to one hundred; he sold them and gave his companion his price.
Imam al-Tabarani recorded this narration; its chain contains a narrator, al-Hasan bin Umarah, who is da'if (weak).
