[Machine] I heard Abdullah bin Mas'ud saying, "The righte ous will depart in groups and those who have doubts will remain, those who do not recognize goodness and do not denounce evil."  

الطبراني:٨٨٨٠ – حَدَّثَنَا أَبُو خَلِيفَةَ ثنا أَبُو الْوَلِيدِ ثنا شُعْبَةُ عَنْ أَبِي إِسْحَاقَ عَنِ الْأَسْوَدِ قَالَ

سَمِعْتُ عَبْدَ اللهِ بْنَ مَسْعُودٍ يَقُولُ «يَذْهَبُ الصَّالِحُونَ أَسْلَافًا وَيَبْقَى أَهْلُ الرِّيَبِ مَنْ لَا يَعْرِفُ مَعْرُوفًا وَلَا يُنْكِرُ مُنْكَرًا»
