Mishkat al-Masabih, hadith 2753

وَعَنِ الْعَدَّاءِ بْنِ خَالِدِ بْنِ هَوْذَةَ أَخْرَجَ كِتَابًا: هَذَا مَا اشْتَرَى الْعَدَّاءُ بْنُ خَالِدِ بْنِ هَوْذَةَ مِنْ مُحَمَّدٍ رَسُولِ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ اشْترى مِنْهُ عبدا أَو أمة لَا دَاءَ وَلَا غَائِلَةَ وَلَا خِبْثَةَ بَيْعَ الْمُسْلِمِ الْمُسْلِمَ. رَوَاهُ التِّرْمِذِيُّ وَقَالَ: هَذَا حَدِيثٌ غَرِيبٌ

This is what al-‘Adda’ b. Khalid b. Haudha brought from Muhammad, God’s Messenger. He bought from him a slave, or a slave woman, with no disease or wickedness, or anything unlawful*, a transaction between two Muslims. Tirmidhi transmitted it, saying this is a gharib tradition. * This might be bad character on the part of the slave or unlawful enslavement.
