abudawud:2761Muḥammad b. ʿAmr al-Rāzī > Salamah / Ibn al-Faḍl > Muḥammad b. Isḥāq

I heard the Messenger of Allah ﷺ say when they (messengers sent by Musaylimah) read the letter of Musaylimah: What do you believe yourselves? They said: We believe as he believes. He said: I swear by Allah that were it not that messengers are not killed, I would cut off your heads.  

أبو داود:٢٧٦١حَدَّثَنَا مُحَمَّدُ بْنُ عَمْرٍو الرَّازِيُّ حَدَّثَنَا سَلَمَةُ يَعْنِي ابْنَ الْفَضْلِ عَنْ مُحَمَّدِ بْنِ إِسْحَاقَ قَالَ

كَانَ مُسَيْلِمَةُ كَتَبَ إِلَى رَسُولِ اللَّهِ ﷺ قَالَ وَقَدْ حَدَّثَنِي مُحَمَّدُ بْنُ إِسْحَاقَ عَنْ شَيْخٍ مِنْ أَشْجَعَ يُقَالُ لَهُ سَعْدُ بْنُ طَارِقٍ عَنْ سَلَمَةَ بْنِ نُعَيْمِ بْنِ مَسْعُودٍ الأَشْجَعِيِّ عَنْ أَبِيهِ نُعَيْمٍ قَالَ سَمِعْتُ رَسُولَ اللَّهِ ﷺ يَقُولُ لَهُمَا حِينَ قَرَآ كِتَابَ مُسَيْلِمَةَ مَا تَقُولاَنِ أَنْتُمَا قَالاَ نَقُولُ كَمَا قَالَ قَالَ أَمَا وَاللَّهِ لَوْلاَ أَنَّ الرُّسُلَ لاَ تُقْتَلُ لَضَرَبْتُ أَعْنَاقَكُمَا

الحاكم:٢٦٣٢أَخْبَرَنَا أَبُو نَصْرٍ أَحْمَدُ بْنُ سَهْلِ بْنِ حَمْدَوَيْهِ الْفَقِيهُ بِبُخَارَى ثنا إِبْرَاهِيمُ بْنُ مَعْقِلٍ النَّسَفِيُّ ثنا مُحَمَّدُ بْنُ عَمْرٍو الرَّازِيُّ وَيُلَقَّبُ بِزُنَيْجٍ ثنا سَلَمَةُ بْنُ الْفَضْلِ الْأَبْرَشُ حَدَّثَنِي مُحَمَّدُ بْنُ إِسْحَاقَ قَالَ

كَانَ مُسَيْلِمَةُ كَتَبَ إِلَى رَسُولِ اللَّهِ ﷺ وَقَدْ حَدَّثَنِي ابْنُ إِسْحَاقَ عَنْ سَعْدِ بْنِ طَارِقٍ الْأَشْجَعِيِّ عَنْ سَلَمَةَ بْنِ نُعَيْمِ بْنِ مَسْعُودٍ الْأَشْجَعِيِّ عَنْ أَبِيهِ نُعَيْمٍ قَالَ سَمِعْتُ رَسُولَ اللَّهِ ﷺ يَقُولُ لِرَسُولَيْ مُسَيْلِمَةَ حِينَ قَرَأَ كِتَابَ مُسَيْلِمَةَ «مَا تَقُولَانِ أَنْتُمَا؟» قَالَا نَقُولُ كَمَا قَالَ قَالَ «أَمَا وَاللَّهِ لَوْلَا أَنَّ الرُّسُلَ لَا تُقْتَلُ لَضَرَبْتُ أَعْنَاقَكُمَا»
