[Machine] I heard a man from the companions of the Prophet ﷺ named Maymun bin Sunbadh saying that the Messenger of Allah ﷺ said, "The best of my ummah (nation) are those who are its worst." He repeated this three times.  

أحمد:٢١٩٨٥ – حَدَّثَنَا عَبْدُ اللهِ حَدَّثَنِي أَبُو أَيُّوبَ صَاحِبُ الْبَصْرِيِّ سُلَيْمَانُ بْنُ أَيُّوبَ حَدَّثَنَا هَارُونُ بْنُ دِينَارٍ عَنْ أَبِيهِ قَالَ

سَمِعْتُ رَجُلًا مِنْ أَصْحَابِ النَّبِيِّ ﷺ يُقَالُ لَهُ مَيْمُونُ بْنُ سُنْبَاذَ يَقُولُ قَالَ رَسُولُ اللهِ ﷺ قَوَامُ أُمَّتِي بِشِرَارِهَا قَالَهَا ثَلَاثًا
