What is disliked regarding keeping slaves

Sayyiduna Abu Hurayrah (may Allah be pleased with him) narrates: A man came and sat with the Prophet (peace and blessings be upon him). The Prophet (peace and blessings be upon him) asked him: "Where are you from?" He replied: I am a Berber. The Prophet (peace and blessings be upon him) said to him: "Get up (and leave me)." The narrator says: The Prophet (peace and blessings be upon him) said this while gesturing like this with his elbow. When the man got up and left him, the Prophet (peace and blessings be upon him) turned to us and said: "Faith does not go beyond their throats."
Ahmad recorded it; its chain contains Abdullah bin Nafi', who is matruk (abandoned), and Yahya bin Ma'in said: his hadith is to be written down. Another narrator is Salih, the freed slave of al-Taw'amah, who suffered from ikhtilat (memory confusion).

Sayyiduna Abdullah bin Amr (may Allah be pleased with him) reports that the Prophet (peace and blessings be upon him) said: "Whoever takes out something to give in charity and then finds no one (to receive it) except a Berber, let him take that charity back."
Ahmad recorded it; its chain contains Ibn Lahi'ah, and his hadith is hasan (good); the rest of its narrators are thiqat (trustworthy).

A freed slave of Rafi' bin Thabit narrates: A man from among the Companions of the Prophet (peace and blessings be upon him) bought a Berber slave girl for two hundred dinars and sent her to Sayyiduna Abu Muhammad (may Allah be pleased with him), who was a Companion of the Prophet (peace and blessings be upon him) and had the honour of taking part in the Battle of Badr; he gave that Berber slave girl to him as a gift. When the slave girl came to him, he said: She is one of those Magians about whom the Prophet (peace and blessings be upon him) forbade, and the polytheists (were also forbidden). The narrator says: I
narrated this report to a man, and he told me that Yahya bin Sa'id had told him that an uncle of his died in the Maghrib (that is, Morocco), and that he was a "Badri" (a veteran of Badr).
Al-Tabarani recorded it; its chain contains a narrator who is not named, and Ibn Lahi'ah.

Sayyiduna Uthman Ghani (may Allah be pleased with him) narrates: I heard the Prophet (peace and blessings be upon him) say: "Wickedness has seventy parts: one part is found in the jinn and humans, and sixty-nine parts are found in the Berbers."
Al-Tabarani recorded it in al-Mu'jam al-Awsat.

In one of his narrations the wording is: "Allah Almighty divided wickedness into seventy parts; He placed sixty-nine parts in the Berbers and one part in all the rest of the people." The chain of the first narration contains Abdullah bin Salih, the scribe of al-Layth; a group declared him da'if (weak) and a group declared him thiqah (trustworthy). The rest of its narrators are thiqat (trustworthy). Its chain also contains al-Muttalib bin Shu'ayb; Ibn Adi said: I have not seen any munkar (denounced) hadith from him except this hadith: "When the honoured man of a people comes to you, honour him."

Sayyiduna Uqbah bin Amir (may Allah be pleased with him) reports that the Prophet (peace and blessings be upon him) said: "Wickedness has seventy parts: sixty-nine parts are for the Berbers, and one part is for (all) the jinn and humans."
Al-Tabarani recorded it; its chain contains Abdullah bin Abd al-Rahman bin Abd al-Hakam, whom I do not know; the rest of its narrators are thiqat (trustworthy), and some of its narrators have weakness.

Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both) narrates: The Prophet (peace and blessings be upon him) said: "Buy slaves and make them partners in their provision, and beware of the Zanj, for their lives are short and their provision is little."
Al-Tabarani recorded it in al-Mu'jam al-Kabir and al-Mu'jam al-Awsat; its chain contains a narrator whom I do not know.

Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both) narrates: Black people were mentioned in the presence of the Prophet (peace and blessings be upon him), and he said: "Leave me alone regarding black people, for the black man lives only for his stomach and his private parts."
Al-Tabarani recorded it; its chain contains Muhammad bin Zakariyya al-Ghalabi, who is extremely da'if (weak). Ibn Hibban declared him thiqah (trustworthy) and said: His narration is to be considered when he narrates from a thiqah (trustworthy) narrator.

Sayyidah Umm Ayman (may Allah be pleased with her) narrates: I heard the Prophet (peace and blessings be upon him) say: "The black man lives only for his private parts or his stomach."
Al-Tabarani recorded it; its chain contains Khalid bin Muhammad, who is from the family of al-Zubayr, and he is da'if (weak).

Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both) narrates: It was said: O Messenger of Allah, what prevents the Abyssinians of Banu al-Mughirah from coming to you, except that they fear you will send them back? The Prophet (peace and blessings be upon him) said: "There is no good in the Abyssinians. When they are hungry they steal, and when they are full they commit fornication. They have two good qualities: feeding people, and bravery in battle."
Al-Tabarani and al-Bazzar recorded it, and the wording of al-Bazzar is: The Prophet (peace and blessings be upon him) said: "There is no good in the Abyssinians. If they are full, they commit fornication; but they have two qualities: feeding people, and strength in battle." The narrators of al-Bazzar are thiqat (trustworthy); about the narrator Awsajah al-Makki there is a difference of opinion that does no harm, and more than one scholar declared him thiqah (trustworthy).

Sayyidah Aishah Siddiqah (may Allah be pleased with her) narrates: I heard the Prophet (peace and blessings be upon him) say: "When the black man is hungry he steals, and when he is full he commits fornication. They have two good qualities: true generosity and courage."
Al-Tabarani recorded it in al-Mu'jam al-Awsat; its chain contains Ibn Ishaq, who is thiqah (trustworthy) but a mudallis, and Ali bin Sa'id al-Razi, about whom al-Daraqutni (may Allah have mercy on him) said: He is not of that standard; he is alone in narrating some things. The rest of its narrators are the narrators of the Sahih.
