Jami` at-Tirmidhi 1216

Narrated 'Abbad bin Laith Al-Karabisi [Al-Basri]: "Abdul Majid bin Wahb narrated to us, he said: 'Al-'Adda' bin Khalid bin Hawdhah said to me: "Shall I not read to you a letter that was written for me from the Messenger of Allah (ﷺ) ?'" He said: 'I said: "Of course." So he took out a letter for me: "This is what Al-'Adda' bin Khalid bin Hawdhah purchased from Muhammad, the Messenger of Allah (ﷺ): He purchased from him a slave' - or - 'a female slave, having no ailments, nor being a runaway, nor having any malicious behavior. Sold by a Muslim to a Muslim.'" [Abu 'Eisa said:] This Hadith is Hasan Gharib, we do not know of it except from 'Abbad bin Laith. More than one of the people of Hadith have reported this Hadith from him
