البيهقي:٢٠٠٥٨ – أَخْبَرَنَا أَبُو الْحُسَيْنِ بْنُ الْفَضْلِ الْقَطَّانُ أنبأ عَبْدُ اللهِ بْنُ جَعْفَرٍ ثنا يَعْقُوبُ بْنُ سُفْيَانَ ثنا أَبُو بَكْرٍ الْحُمَيْدِيُّ ثنا سُفْيَانُ ثنا أَيُّوبُ بْنُ عَائِذٍ الطَّائِيُّ قَالَ قُلْتُ لِلشَّعْبِيِّ رَجُلٌ نَذَرَ أَنْ يَنْحَرَ ابْنَهُ؟ فَقَالَ

لَعَلَّكَ مِنَ الْقَيَّاسِينَ مَا عَلِمْتُ أَحَدًا مِنَ النَّاسِ كَانَ أَطْلَبَ لَعِلْمٍ فِي أُفُقٍ مِنَ الْآفَاقِ مِنْ مَسْرُوقٍ قَالَ لَا نَذْرَ فِي مَعْصِيَةٍ
