One who is better than me, Abu Qatada, informed me that the Messenger of Allah ﷺ said to Ammar bin Yasir, "The transgressing party will kill you."
حدثنا حسن بن يحيى من أهل مرو أخبرنا النضر بن شميل حدثنا شعبة عن أبي مسلمة عن أبي نضرة
أخبرني من هو خير مني أبو قتادة أن رسول الله ﷺ قال لعمار بن ياسر تقتلك الفئة الباغية
Its isnad is sahih. Hasan bin Yahya Marwazi was deemed trustworthy by Ibn Hibban, and Ibn Najjar remained silent about him in his supplement to Tarikh Baghdad. It was mentioned earlier that Ahmad paired him with Yahya bin Ishaq. Here a corroborating narrator is mentioned for him, namely Muhammad bin Jafar, from Shubah, as in the preceding hadith.
