Malik related to me from Suhayl ibn Abu Salih from his father from Abu Hurayra that the Messenger of Allah ﷺ said, "When you hear a man say, 'The people are ruined,' he himself is the most ruined of them all."
أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ إِذَا سَمِعْتَ الرَّجُلَ يَقُولُ هَلَكَ النَّاسُ فَهُوَ أَهْلَكُهُمْ
