[Machine] That the Messenger of Allah ﷺ killed a Muslim man with a covenant (of protection) and said, "I am the most honorable of those who fulfill their covenants." This is an error from two aspects: one is that it connects the narration to Ibn Umar, when in fact it is from Ibn Baylamani's narration that is connected to the Prophet ﷺ, and the other is that it is narrated from Ibrahim from Rabi'ah, when in fact Ibrahim narrates it from Ibn al-Munkadir. The burden of this narration falls on Ammar ibn Matar al-Rahawi, as he used to alter the chains of narration and steal hadiths, until this became frequent in his narrations, and it becomes invalid as evidence.  

أَنَّ رَسُولَ اللهِ ﷺ قَتَلَ مُسْلِمًا بِمُعَاهِدٍ وَقَالَ أَنَا أَكْرَمُ مَنْ وَفَى بِذِمَّتِهِ هَذَا خَطَأٌ مِنْ وَجْهَيْنِ أَحَدُهُمَا وَصَلَهُ بِذِكْرِ ابْنِ عُمَرَ فِيهِ وَإِنَّمَا هُوَ عَنِ ابْنِ الْبَيْلَمَانِيِّ عَنِ النَّبِيِّ ﷺ مُرْسَلًا وَالْآخَرُ رِوَايَتُهُ عَنْ إِبْرَاهِيمَ عَنْ رَبِيعَةَ وَإِنَّمَا يَرْوِيهِ إِبْرَاهِيمُ عَنِ ابْنِ الْمُنْكَدِرِ وَالْحَمْلُ فِيهِ عَلَى عَمَّارِ بْنِ مَطَرٍ الرَّهَاوِيِّ فَقَدْ كَانَ يُقَلِّبُ الْأَسَانِيدَ وَيَسْرِقُ الْأَحَادِيثَ حَتَّى كَثُرَ ذَلِكَ فِي رِوَايَاتِهِ وَسَقَطَ عَنْ حَدِّ الِاحْتِجَاجِ بِهِ
