[Machine] I heard the Messenger of Allah ﷺ say, "O Allah, ignite the Quraysh with 'Ammar. Indeed, the killer of 'Ammar and the one who takes his belongings will be in the Fire." 'Abd al-Rahman ibn al-Mubarak, who is trustworthy and reliable, narrated this incident from Mu'tamir, from his father, from Abu Bakr. If this narration is preserved, then it is authentic according to the conditions of the two scholars (Al-Bukhari and Muslim), and they did not include it in their collections. But people have only narrated it from Mu'tamir, from Layth, from Mujahid, based on the condition of Al-Bukhari and Muslim.  

سَمِعْتُ رَسُولَ اللَّهِ ﷺ يَقُولُ «اللَّهُمَّ أُولِعَتْ قُرَيْشٌ بِعَمَّارٍ إِنَّ قَاتِلَ عَمَّارٍ وَسَالِبَهُ فِي النَّارِ» وَتَفَرَّدَ بِهِ عَبْدُ الرَّحْمَنِ بْنُ الْمُبَارَكِ وَهُوَ ثِقَةٌ مَأْمُونٌ عَنْ مُعْتَمِرٍ عَنْ أَبِيهِ «» فَإِنْ كَانَ مَحْفُوظًا فَإِنَّهُ صَحِيحٌ عَلَى شَرْطِ الشَّيْخَيْنِ وَلَمْ يُخَرِّجَاهُ وَإِنَّمَا رَوَاهُ النَّاسُ عَنْ مُعْتَمِرٍ عَنْ لَيْثٍ عَنْ مُجَاهِدٍعلى شرط البخاري ومسلم
