It was narrated that 'Abdul-Majid bin Wahb said:"Adda' bin Khalid bin Hawdhah said to me: 'Shall I not read to you a letter that the Messenger of Allah (ﷺ), wrote to me?' I said: 'Yes.' So he took out a letter. In it was: 'This is what 'Adda' bin Khalid bin Hawdhah bought [from] Muhammad the Messenger of Allah (ﷺ) He bought from him a slave' or 'a female slave, having no ailments, nor being a runaway, not having any malicious behavior. Sold by a Muslim to a Muslim.'"
حَدَّثَنَا مُحَمَّدُ بْنُ بَشَّارٍ، حَدَّثَنَا عَبَّادُ بْنُ لَيْثٍ، صَاحِبُ الْكَرَابِيسِيِّ حَدَّثَنَا عَبْدُ الْمَجِيدِ بْنُ وَهْبٍ، قَالَ قَالَ لِي الْعَدَّاءُ بْنُ خَالِدِ بْنِ هَوْذَةَ أَلاَ نُقْرِئُكَ كِتَابًا كَتَبَهُ لِي رَسُولُ اللَّهِ ـ صلى الله عليه وسلم ـ . قَالَ قُلْتُ بَلَى . فَأَخْرَجَ لِي كِتَابًا فَإِذَا فِيهِ " هَذَا مَا اشْتَرَى الْعَدَّاءُ بْنُ خَالِدِ بْنِ هَوْذَةَ مِنْ مُحَمَّدٍ رَسُولِ اللَّهِ ـ صلى الله عليه وسلم ـ اشْتَرَى مِنْهُ عَبْدًا أَوْ أَمَةً لاَ دَاءَ وَلاَ غَائِلَةَ وَلاَ خِبْثَةَ بَيْعَ الْمُسْلِمِ لِلْمُسْلِمِ " .
