Sunan of Abu Dawood Book 15, Hadith 2762

حَدَّثَنَا مُحَمَّدُ بْنُ كَثِيرٍ، أَخْبَرَنَا سُفْيَانُ، عَنْ أَبِي إِسْحَاقَ، عَنْ حَارِثَةَ بْنِ مُضَرِّبٍ، أَنَّهُ أَتَى عَبْدَ اللَّهِ فَقَالَ مَا بَيْنِي وَبَيْنَ أَحَدٍ مِنَ الْعَرَبِ حِنَةٌ وَإِنِّي مَرَرْتُ بِمَسْجِدٍ لِبَنِي حَنِيفَةَ فَإِذَا هُمْ يُؤْمِنُونَ بِمُسَيْلِمَةَ ‏.‏ فَأَرْسَلَ إِلَيْهِمْ عَبْدُ اللَّهِ فَجِيءَ بِهِمْ فَاسْتَتَابَهُمْ غَيْرَ ابْنِ النَّوَّاحَةِ قَالَ لَهُ سَمِعْتُ رَسُولَ اللَّهِ صلى الله عليه وسلم يَقُولُ ‏ "‏ لَوْلاَ أَنَّكَ رَسُولٌ لَضَرَبْتُ عُنُقَكَ ‏"‏ ‏.‏ فَأَنْتَ الْيَوْمَ لَسْتَ بِرَسُولٍ فَأَمَرَ قَرَظَةَ بْنَ كَعْبٍ فَضَرَبَ عُنُقَهُ فِي السُّوقِ ثُمَّ قَالَ مَنْ أَرَادَ أَنْ يَنْظُرَ إِلَى ابْنِ النَّوَّاحَةِ قَتِيلاً بِالسُّوقِ ‏.‏

Narrated Abdullah ibn Mas'ud: Harithah ibn Mudarrib said that he came to Abdullah ibn Mas'ud and said (to him): There is no enmity between me and any of the Arabs. I passed a mosque of Banu Hanifah. They (the people) believed in Musaylimah. Abdullah (ibn Mas'ud) sent for them. They were brought, and he asked them to repent, except Ibn an-Nawwahah. He said to him: I heard the Messenger of Allah (ﷺ) say: Were it not that you were not a messenger, I would behead you. But today you are not a messenger. He then ordered Qarazah ibn Ka'b (to kill him). He beheaded him in the market. Anyone who wants to see Ibn an-Nawwahah slain in the market (he may see him)
