حَدَّثَنَا قُتَيْبَةُ بْنُ سَعِيدٍ، حَدَّثَنَا جَرِيرٌ، عَنْ مُطَرِّفٍ، عَنِ الشَّعْبِيِّ، عَنْ عَدِيِّ بْنِ حَاتِمٍ ـ رضى الله عنه ـ قَالَ قُلْتُ يَا رَسُولَ اللَّهِ مَا الْخَيْطُ الأَبْيَضُ مِنَ الْخَيْطِ الأَسْوَدِ أَهُمَا الْخَيْطَانِ قَالَ ‏
"‏ إِنَّكَ لَعَرِيضُ الْقَفَا إِنْ أَبْصَرْتَ الْخَيْطَيْنِ ‏"‏‏.‏ ثُمَّ قَالَ ‏"‏ لاَ بَلْ هُوَ سَوَادُ اللَّيْلِ وَبَيَاضُ النَّهَارِ ‏"‏‏.‏
