حَدَّثَنَا سُفْيَانُ بْنُ وَكِيعٍ، حَدَّثَنَا أَحْمَدُ بْنُ بَشِيرٍ، وَأَبُو أُسَامَةَ عَنْ مِسْعَرٍ، عَنْ زِيَادِ بْنِ عِلاَقَةَ، عَنْ عَمِّهِ، قَالَ كَانَ النَّبِيُّ صلى الله عليه وسلم يَقُولُ " اللَّهُمَّ إِنِّي أَعُوذُ بِكَ مِنْ مُنْكَرَاتِ الأَخْلاَقِ وَالأَعْمَالِ وَالأَهْوَاءِ " . قَالَ هَذَا حَدِيثٌ حَسَنٌ غَرِيبٌ . وَعَمُّ زِيَادِ بْنِ عِلاَقَةَ هُوَ قُطْبَةُ بْنُ مَالِكٍ صَاحِبُ النَّبِيِّ صلى الله عليه وسلم .
