4519Abu DawoodSahih Maqtu' (Al-Albani)حَدَّثَنَا الْحَسَنُ بْنُ عَلِيٍّ، حَدَّثَنَا سَعِيدُ بْنُ عَامِرٍ، عَنِ ابْنِ أَبِي عَرُوبَةَ، عَنْ قَتَادَةَ، بِإِسْنَادِ شُعْبَةَ مِثْلَهُ زَادَ ثُمَّ إِنَّ الْحَسَنَ نَسِيَ هَذَا الْحَدِيثَ فَكَانَ يَقُولُ لاَ يُقْتَلُ حُرٌّ بِعَبْدٍ " Qatadah transmitted the tradition mentioned above through a chain of narrators like that of Shu'bah. This version adds:Then al-Hasan forgot this tradition, and he used to say: A free man is not to be killed for a slave.Reference: Sunan Abi Dawud 4517 In-book : Book 41, Hadith 24 English translation : Book 40, Hadith 4503
