حَدَّثَنَا عِيسَى بْنُ مُحَمَّدٍ الرَّمْلِيُّ، وَابْنُ، عَوْفٍ - وَهَذَا لَفْظُهُ - قَالاَ حَدَّثَنَا الْفِرْيَابِيُّ، عَنْ سُفْيَانَ، عَنْ ثَوْرٍ، عَنْ رَاشِدِ بْنِ سَعْدٍ، عَنْ مُعَاوِيَةَ، قَالَ سَمِعْتُ رَسُولَ اللَّهِ صلى الله عليه وسلم يَقُولُ ‏"‏ إِنَّكَ إِنِ اتَّبَعْتَ عَوْرَاتِ النَّاسِ أَفْسَدْتَهُمْ أَوْ كِدْتَ أَنْ تُفْسِدَهُمْ ‏"‏ ‏.‏ فَقَالَ أَبُو الدَّرْدَاءِ كَلِمَةٌ سَمِعَهَا مُعَاوِيَةُ مِنْ رَسُولِ اللَّهِ صلى الله عليه وسلم نَفَعَهُ اللَّهُ تَعَالَى بِهَا ‏.‏

Narrated Abdullah ibn Mas'ud

Zayd ibn Wahb said: A man was brought to Ibn Mas'ud. He was told: This is so and so, and wine was dropping from his beard. Abdullah thereupon said: We have been prohibited to seek out (faults). If anything becomes manifest to us, we shall seize it.
