"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.'"
لِي الْعَدَّاءُ بْنُ خَالِدِ بْنِ هَوْذَةَ أَلاَ نُقْرِئُكَ كِتَابًا كَتَبَهُ لِي رَسُولُ اللَّهِ ﷺ قَالَ قُلْتُ بَلَى فَأَخْرَجَ لِي كِتَابًا فَإِذَا فِيهِ هَذَا مَا اشْتَرَى الْعَدَّاءُ بْنُ خَالِدِ بْنِ هَوْذَةَ مِنْ مُحَمَّدٍ رَسُولِ اللَّهِ ﷺ اشْتَرَى مِنْهُ عَبْدًا أَوْ أَمَةً لاَ دَاءَ وَلاَ غَائِلَةَ وَلاَ خِبْثَةَ بَيْعَ الْمُسْلِمِ لِلْمُسْلِمِ
