Adda bin Khalid bin Hawdha said to me, "Shall I read to you a document that the Messenger of Allah ﷺ wrote for me?"I replied, "Yes, please."So he brought out a document that read, "This is what Adda bin Khalid bin Hawdha purchased from Muhammad, the Messenger of Allah ﷺ. He purchased from him a slave," or "a slave-girl, with no hidden disease, no deceit, and no immoral conduct, a sale of one Muslim to another."
قال لي العداء العداء بن خالد بن هوذة: ألا أقرئك كتابا كتبه لي رسول الله ﷺ! قال: قلت: بلي. فأخرج إلي كتابا هذا ما اشترى العداء بن خالد بن هوذة من محمد رسول الله ﷺ، اشترى منه عبدا أو أمة، لا داء، ولا غائلة، ولا خبثة، بيع المسلم للمسلم.
Tirmidhi (1216), Ibn Majah (2251), and Bayhaqi (5/327) all narrated it through Abbad bin Layth, the companion of Karabisi, who said, "Abdul-Majid bin Wahb narrated to us," and he related it. Abbad bin Layth is disputed, but he is hasan al-hadith when he does not err, and he has been corroborated. Bayhaqi narrated it through the hadith of Uthman Shahham, from Abu Raja Attaridi, who said that Adaa bin Khalid said something similar. With this corroboration this hadith becomes hasan, even though it is known primarily through the hadith of Abbad bin Layth, as Bayhaqi said.It is further strengthened by the ruling of Uthman bin Affan, which is what Malik narrated from Yahya bin Saeed, from Salim bin Abdullah, that Abdullah bin Umar sold a slave boy of his for eight hundred dirhams, selling him with a disclaimer of liability. The buyer then said to Abdullah bin Umar, "This boy has a defect you did not name." So they brought their dispute to Uthman bin Affan. The man said, "He sold me a slave who has a defect he did not name to me." Abdullah bin Umar said, "I sold him with a disclaimer of liability." So Uthman bin Affan ruled against Abdullah bin Umar that he must take an oath swearing, "I sold him this boy without knowing of any defect in him." Abdullah refused to take the oath for him, and so he took the slave back. Abdullah bin Umar later sold him for one thousand five hundred dirhams. End of narration.Malik said, "The matter agreed upon among us is that whoever sells a slave, male or female, or an animal, with a disclaimer of liability, is absolved of every defect, unless he knew of that defect and concealed it. If he knew of a defect and concealed it, his disclaimer does not benefit him, and what he sold is to be returned to him." End of statement.
